Reducing Solr indexing delay

Question

By default the example Solr application included with version 1.4.1 takes two minutes to process documents sent to the index. I've seen other servers configured to take 3+ minutes. Where can you change change this to zero or 15 seconds?

Answer 1

You need to adjust autocommit option in your solrconfig.xml. By default its:

<autoCommit> 
  <maxDocs>2000</maxDocs>
  <maxTime>120000</maxTime> 
</autoCommit>

maxTime is what you need, it's in miliseconds.
