Hi,
I am tinkering on having the option of using solr for the search functionality of osclass. I have good knowledge of how solr works but I have basic php knowledge so it would take me months to integrate it by myself. I have taken a look at some of the code and have a good idea on how it would be done. Maybe two to three day's work for someone who is good in php.
Why use solr?
Relevant search result e.g. when you search for car, actual cars are placed on the top of search results and not those House with car garage (just an example which can happen)
Use of synonym file. define car and automobiles as synonyms and when you search for car, those automobile ads will be part of your search result
Faceting - grouping of results
Elevate - put an item on top of search result, great for premium ads
Fast!
