I am amazed at how anal this site is about making thread titles coherent to makes searches more reliable when the search function on this site is totally worthless. Any worthwhile search of the site can only be done via Google...IMHO. Maybe that's the way the owner planned it.

He/they have no real choice in the matter. VB runs ONLY on a MySQL(+InnoDB backend) RDBMS. It isn't even OBJECT-Relational as far more powerful PostgreSQL is.
Now the crux of the matter is that a(ny) RDBMS needs to
build indices if on-box searches are not to drive a server to its knees, resource-load-wise.
VB does make an attempt. You can see 'keywords' associated with postings.
Even so "you can't get there from here" because as the site content expands, the indices needed to categorize it eventually grow larger than the data they are trying to index! This seems to be under progressively harder applied limits as time passes. Searches have gone from decent to poor to nearly useless over the past 4 or 5 years.
Catch 22.
You'd have a seriously hard time trying to support a collection of forums as active as PM even on a "native"
Object Database, such as Z-Server/Medusa, where Dublin Core Metadata replaces indices. It just isn't fast enough in OTHER areas. Actually, it is dead-SLOW, and needs "SQUID" to keep it from falling on its nose. Other caching accelerators don't do as well (BTDTGGTS). Squid has an arcane feature they lack that allows Zserver/Medusa to keep it aware "more cheaply" as to just how current its cached data is.
Catch 23.
End of the day, the massive google HP in the indexing game is all there is that can keep up.
Google is deeply "aware" of PM activity, watches it as it happens in order to do its own indexing effectively. Google has the server HP to JF dooo that.
No other search engine "race" even comes close.
Catch 24
No further effort on our part, nor more than what VB and PM's admin already do as to "salting" for google crawlers and trackers is required.
I have no special insight as to whether that was PM-admin's first-choice or not.
It is, however, a "no other realistic option" situation, like THAT or not.
Catch 25
