Subject Baseline vs. Incremental Indexing
Date Fri, 29 Apr 2011 18:58:25 GMT

Currently we index new/updated records every 30 minutes (I am referring to
this as incremental/partial index) -- i.e., records will be added to an
existing index. Are there any benefits in creating a new index (i.e., delete
the existing index and create it) from a performance point of view everyday
or a week?

In other search system I worked with, incremental updates are generated in a
small file. When the server is restarted, each update in the small files
need to be applied. When there are several small files to be applied, the
restart process could take a few minutes to complete so the recommendation
was to run baseline process every night. I'm wondering if this is the case
with Solr as well?
