> So, these are my 3 questions: > 1. Does Solr provide searching among different count fields with different > types like in WHERE condition? Yes. As long as these are not full-text you should use filter queries for these, e.g. &q=*:* &fq=country:USA &fq=language:SPA &fq=age:[30 TO 40] &fq=(bool_field1:1 OR bool_field2:1) The reason why I put multiple "fq" instead of one long is to optimize for caching of filters > 2. Does Solr provide such sorting, that depends on other fields (like sums > in ORDER BY), other words - does it provide any kind of function, which is > used to sort results from q1? Yes. In trunk version you can sort by function which can do sums and all crezy things &sort=sum(product(has_photo,10),if(exists(query($agequery)),50,0)) asc&agequery=age:[53 TO *] See http://wiki.apache.org/solr/FunctionQuery for more functions But you could also to much of this through boost queries &sort=score desc &bq=language:FRA^50 %bq=age:[53 TO *]^20 > 3. Does Solr provide realtime index updating or updating every N minutes? Sure, there is Near Real-time indexing in TRUNK (coming 4.0) Jan
