Greetings- I hate having to ask stupid questions when there is such a large data base of great info available here. My problem is that I have a very difficult time finding specific posts that I have read in the past. For instance, I know that I saw a PDF of the entire 5235 crossover manual here , but after trying several searches of "5235", "5235 crossover", "electronic crossover", etc, etc. etc.,I still can't find it. I also remember Giskard posting schematics of some new and improved 43xx crossover that he had designed, can't find those either. Could someone please give me a basic primer on searching for specific info, I must be doing something wrong. Thank you, wpod

Yes, searching can be painful here. I have no real solution, I help myself with bookmarks or I look into "Find all posts by ...".

We've lamented this "feature" many times. There is no architechture of this database, so things get put in the most unexpected places!

Maybe there is a way to add a "Search posts with attachments" choice? That would really thin-down the hits.

Hoping Don and/or John Nebel sees this...

When ever you are looking for manuals go here first. It's much easier

It should be added to the JBL Pro links in the Tech Section.


For the improved 4344/45 schematics do a search for 4344/45 they are imbedded in the threads. You really need a good memory to find alot of this stuff or you can simply add the thread to you Favorites in a Lansing folder in you browser.

Actually, this forum is built upon a very structured relational database at its core and the forum itself has a fairly comprehensive structure imposed upon it through sub forum definitions. The problem occurs when members do not follow the sub forum definitions in placing new posts or hijack an exisiting thread to take it to a new topic that should rightly be found in a different sub forum. The moderators try to address this, but with hundreds of posts a day, it is not possible to catch everything.

That being said, the search feature actually contains a fair bit of power. To begin with, always try the "Advanced Search" if the basic seach dialog box returns too many hits or inappropriate results. The key to any successful search is trying to narrow down the scope by applying any distinguishing information that you can think of. For example, if you can remember who posted the information, or roughly when it was posted, you can add these paramaters in the advanced search. The same thing applies to the sub forums in which it may be located or whether you remember if the thread was very active (i.e. rough number of replies).

If you still have too many hits, you can try sorting the results by forum, date, relevance, member, number of replies etc to help sift through them. I always set the results to be shown as individual posts instead of threads. That way, you will see the specific instance where your search term was used in the results summary and not have to open and hunt through every thread that came back with a positive hit.

Using the above, I typed in 5235 Manual and found the following post and thread in less than a minute. I assume that this is what you were looking for.

To Bo, unfortunately, limiting searches to posts with attachments only is currently not possible.

I typed in 5235 Manual and found the following post and thread in less than a minute. Dammit, Don! :bash: I tried a number of search strings myself, but they all included "crossover" and that returned a bunch of trash hits. Your post reminds us how search strings need to be specific, tried and revised until the objective is found.


To Bo, unfortunately, limiting searches to posts with attachments only is currently not possible.Yea, that was my expectation. It would be a nice future feature...

Thanks, Don.

In long threads, a secondary "Search this thread" using the same search terms brings up the relevant individual posts quickly....

These are all useful and relevant tips, Don. I usually have very good luck with search, and now I think I'll do even better with your refresher course.

Some further features of the search function:


You can search for phrases by placing the text in quotes. For example a search for "Studio Monitor" will only return hits for that specific phrase.

You can include wild cards * in the search to find a range of terms. For example *speaker* would return speaker, loudspeaker, speakers, etc.

You can include the following logical separators between words AND, OR, XOR, -. The - character stands for "not" and it should be noted that the default operator for multi-word searches is AND.


I also have some further advice for performing searches based on the original example. One way of looking at structuring a search is to strike a balance between narrowing down the scope to the degree possible and preventing the inadvertent exclusion of relevant results. The above example started with a search for 5235, but when that returned too many results, tried to narrow the scope by searching for 5235 crossover. That search actually has a high probability of excluding relevant posts while not really narrowing the scope. The 5235 is a crossover, so adding that term is actually redundant. It's not as if there would be dozens of posts on this forum using the specific number 5235 in a manner that does not refer the the JBL crossover. Adding a keyword that is effective in reducing the search scope means that this new term must modify the original keyword to represent a relevant subset and not just be a synonym.

To further elaborate on why the modified search was problematic, some people have likely posted about the 5235 and never added the term crossover. They may have assumed that the audience members targeted by their message would know what this is and those posts would be inadvertently excluded in the modified search. Further, some people spell crossover as cross over, cross-over, Xover or just use the term network and all of these posts would be excluded by that search. Going back to basics, what the originator of this thread was looking for was a manual for the 5235. Therefore a search for the keyword 5235 and modifying it with the keyword manual to restrict the search to posts that mentioned both seemed like a good starting point and appeared to work.

This is not how it is functioning for me now.

I get the exact same search results for the quoted phrases "Monitor Studio" as for "Studio Monitor" which is only true because they are being considered as two separate keywords, not a specific phrase.

When I did an advanced search for "felt surround" the search results were for "felt, surround" (note the separating comma)

The first hit was my posting about a curious speaker cone with a felt edge-surround. Which would be expected to appear first since it has the two keywords closest to each other.

But other hits were simply posts that included both words.

Did the search engine change?
Is it returning less specific results because my number of hits was so low?

My bad. There are two types of search engines available for Vbulletin. One is a custom engine built by the developers and the second uses the MySQL seach engine of the database. I have set up the forum using the custom engine which does not support exact searches. I'm looking into the ramifications of switching engines, but it does not look good. From a quick look at the Vbulletin support forum, there seems to be numerous posts about problems using the MySQL search engine. I'll keep you posted.

no Search results when I try a forum search for "075", "375", "L65" or "but".
I guess these are just too short for the search engine, but sure would be useful for us.

I just had zero luck searching for a thread about the JBL Story book by John Eargle. I tried all the tricks: JBL Story (in quotes); JBL Story Book Eargle (all with "and" between) and everything else I could think of.

Every GD time I got the same results - 20 effing pages:

Maybe that's causing the problem I'm having? What good is an "inexact search"?

Sounds like an oxymoron!

Don - are you saying that using "quote" marks or any of the logical separators you listed won't work with the custom engine?

Its pretty frustrating - I tried to do a search for "xlr" (no quotes) - because I remember some folks mentioned a good adapter to use on the 5235 active crossover to get away from the balanced type connectors for home use.

Well, no results on my search for xlr ...

Have you tried letting the local Google search parse the Lansing site??

I made a demo of what I am talking about here:

http://www.hjames.net/forum.html (http://www.hjames.net/forum.html)

I set it to search the whole site beginning at http://audioheritage.org/

Type XLR into THAT box and google returns all the occurances of XLR on the site!

Type XLR + 5235 and it returns just two threads ...

and this turned out to be the thread I needed -

In investigating the search options a few days ago, it would appear that I inadvertently set the seach type to MySQL "Full Text Search". The default minimum word size for this search engine is 4 letters so that XLR, JBL etc. would return null results. I cannot change this word size since it must be done by a database administrator. Therefore, I have set it back to the vbulletin search type so that three letter searches are possible again. For example, a search for "XLR" returns dozens of relevant posts.

Ahah... I had noticed the 4 character limit as well. Wait a few seconds and Don pops in with some information! Maybe its not the solution, but it is the answer. Ill continue with what I was going to say anyway.

Yes, Google is pretty good about finding stuff. You just have to know how to do it. Searching a particular domain is quite useful and pretty easy. Just add the phrase 'site:xxx.xxx.xxx' to the search string.

Google this-> JBL site:audioheritage.org

The problem with google however is that you cant then sort by date. Yes there is a 'look in the last 3 months' option, but that option seems to be practically worthless.

Interestingly the sort by date in a 'groups' search is pretty good. However the 'site' command does not work. Whats with that!

I am only semi-regular on this board so I dont read all of the new posts on a regular basis (BTW, lots of great posts here). This new search rule is a slight kink for me because I was using the search engine to find topics where someone might be using our product (we make the Woofer Tester). I might then pop in with a tip or two. Anyhow, the acronym 'WT2' is now too short.

- Don has just changed the search engine so that 3 letter acronyms are now searchable .

- A search for WT2 returned a few pages of results .

Any update or improvements in the search function here??? :blink:

I just tried a search but putting search item terms or phrase in quotes (for an exact search) made no difference.

Why no new posts here in 3-1/2 years???? Huh?

Most likely because anyone attempting such a search is probably using the Google Advanced Search option using the "audioheritage.org" domain and having good results! Though I would prefer if, like many sites, searching this site via Google was an embedded option.

Try this, use Google to search for JBL related subjects, but add site:audioheritage.org to the end of the search term. It works. Example:
http://jbl l250 site:audioheritage.org
