When a phrase is too small, forum search will ignore it (even though I have set the lowest keyword allowable to 3 letters now). If it's used along with another word for example "CAI gain ", "HFC review" or "Oil change", the 3 letter words will no longer be omitted (like before). I just tried "oil change" and it seems to work well. Take a look:
Please note, you'll still get search result for the word "oil" and "change" as well. That's unavoidable.
Basically, if you're searching for a small word, don't forget to add another word which will reduce the chances of a broad search result. Also, ALWAYS type your keywords and then select Titles only. You can even narrow your search by clicking on the appropriate section.
I know VBulletin search isn't perfect. Hopefully the next version of
VB has better search options.
Also, I will looking into the that custom google search for our forum.
Thanks
