[TYPO3-english] IndexedSearch vs mnoGoSearch & PowerSearch

[Vahan Amirbekyan]

Dear All,
for the last year I am using indexed_search as a search engine across 
several projects.
For high-performance projects where search function is one of primary 
features indexed_search's perfermance falls behind today's performance 
expectations for quality and speed. especially its fulltext option and cases 
of 3 and more search keywords.
I started looking around and found two options to consider to replace 
indexed_search with:
1. mnoGoSearch (mnogosearch) by Dmitry Dulepov
2. PowerSearch (powersearch) by Knut Moeller and Norbert Sendetzky

I would apprecaite your comments to these options ( or any others ) and any 
inside into why for example mnoGoSearch would be faster than indexed_search 
and for what case, if powersearch is mature to be deployed in PROD 
environment and so on.

thank you in advance
