XF 1.2 Search integrity here on Xenforo?

[Ludachris]

I'm wondering if this is how the search will function when I switch my site over from vb... I'm a little concerned. Is there a document that explains how the search functionality works here? One thing I noticed is that I sometimes get unexpected results. How does the search handle multiple keyword terms and partials? And how does the upgraded search differ?

It looks like the doing a search for "announcement" here in the forums returns this post, but I'm not sure why since that keyword is not in the post:

Enhanced Search is installed here, which included the stemming analyzer function.

The stemming analyzer separates words based on spaces and some punctuation, but goes a step farther and reduces words to their root. This allows a search for "tests" to automatically match results for "test", "testing", "tested", and other similar words. As the algorithm to find the root of a word is language-dependent, this analyzer only works correctly with English content.

The word 'announced' is in the first post.

That explains it. Is there a way to override that using single quotes or some other characters?

It only works for the Enhanced Search add-on.
If you use standard MySQL search on your own site you don't need to worry about it.

Even with ES, you do need to enable it, but there's no way to disable it on a per search basis (it's likely that the root word is all that's been indexed).

I have a forum with nearly 4 million posts and I believe the Enhanced Search is suggested. So I'm trying to figure out how it will work.

As Mike said, you can disable the stemming analyzer:
