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

Solr is going to return it's results in a syntax easily parsible using SimpleXml. You could also use the SolPHP client library: http://wiki.apache.org/solr/SolPHP.

Solr is really quite efficient. I suggest putting as much data into your Solr index as necessary to retrieve everything in one hit from Solr. This could mean much less database traffic for you.

If you've installed the example Solr application (comes with Jetty), then you can develop Solr queries using the admin interface. The URI of the result is pretty much what you'd be constructing in PHP.

The most difficult part when beginning with Solr is getting the solrconfig.xml and the schema.xml files correct. I suggest starting with a very basic config, and restart your web app each time you add a field. Starting off with the whole schema.xml can be confusing.
