Multi word queries is the bread and butter of Solr/Lucene, so I'm not sure I understand the complete issue here. For clarity, is 'abstract' the name of your default text field, or is your query
q=abstract: mouse genome if the latter, my thought was is it possible that the query is being converted into a query of q=abstract:mouse genome where mouse is looked for in the field abstract, and genome is compared to the default text field. This is a stab in the dark, I don't know what your data looks like. You say it doesn't work the way you expect, but you don't really say what you do see. Are you getting zero results, or fewer than you expected, or only results that match all fields (the AND proposition)? -- View this message in context: http://lucene.472066.n3.nabble.com/Multi-Word-searches-in-Solr-tp1918802p1918915.html Sent from the Solr - User mailing list archive at Nabble.com.
