Questions about SOLR documents and some more

Question

Website: Classifieds website (users may put ads, search ads etc)

I plan to use SOLR for searching and then return results as ID nr:s only, and then use those ID nr:s

Answer 1

As suggested by others you can store and index your mysql data and can run query in solr index, thus making mysql unnecessary to use. You don't need to just store and index ids and query and get ids and then run mysql query to get additional data against that id. You can just store other data corresponding to ids in solr itself.

Regarding solr PHP client, then you don't need to use and it is recommended to directly use REST like Solr Web API. You can use PHP function like file_get_contents("http://IP:port/solr/#/core/select?q=query&start=0&rows=100&wt=json") or use curl with PHP if you need to. Both ways are almost same and efficient. This will return data in json as wt=json. Then use PHP function json_decode($returned_data) to get that data in object.

If you need to ask anything just reply.
