Erik Hatcher updated SOLR-1485:
-------------------------------
Attachment: PayloadTermQueryPlugin.java
This class adds a QParserPlugin to support creating PayloadTermQuery's.
This can be registered in solrconfig.xml like this:
<queryParser name="payload"
class="org.apache.solr.search.PayloadTermQueryPlugin"/>
A custom Similarity is needed to score payloads (not provided with this issue).
Once everything is lined up right (payload indexed, similarity with
scorePayload implemented), a query like this can be used:
http://localhost:8983/solr/select?q={!payload%20f=payloads%20func=avg}foo&debugQuery=true
As can be seen with this explanation:
1.4450715 = (MATCH) fieldWeight(payloads:foo in 0), product of:
4.709331 = (MATCH) btq, product of:
0.70710677 = tf(phraseFreq=0.5)
6.66 = scorePayload(...)
0.30685282 = idf(payloads: foo=1)
1.0 = fieldNorm(field=payloads, doc=0)
