If i strip all html tags and filter more stop words, will the search be more accurate? Actually my fulltext stats returns some like: font from <font> tags i guess, and other garbage. If i do that, will i improve the speed of my search?
What do you mean 'accurate' ? You need be yourself a bit more 'accurate' when asking:) You need to provide more information about your problem.
For example, version of postgresql, size of collection you indexed, explain analyze for your query, 'garbage' you got, etc. This is not difficult - just copy'n paste work.
Thanks! Ps: I cannot use other tools like MNOsearch, lucene, etc...because i have no root pass to my server.
