Hello all. I have a question about using an external database to store just the fields returned during the GET_FIELDS stage.
We are using Solr to search an index with a good number of columns. That returns some ids, the scores and some facets. The ids are then passed to a custom DatabaseComponent that queries a SQL Database for the ids and returns the data that we actually want to display. However, to make this work (and it does) we have had to make some values public in the ResponseBuilder and elsewhere, so that we can pull the ids out and use them in the GET_FIELDS stage to actually fetch the SQL data. The values we are exposing and messing with in our code shouldn't be messed with, really, being cited as "shared" or "should be treated as shared." After a fair amount of investigation, however, we have been unable to find another way to pull the results from the GET_IDS *without* reaching into the ResponseBuilder like we have. This seems like a serious oversight to me, and I am afraid that we just don't know enough about how to accomplish the same results without modifying Solr. So the main question is, Is there a way to use an external database component without exposing some package protected variables inside Solr? -- View this message in context: http://lucene.472066.n3.nabble.com/How-to-use-an-External-Database-for-Fields-tp3468308p3468308.html Sent from the Solr - User mailing list archive at Nabble.com.
