I am a new Solr user and wonder if anyone can help me these questions. I used
Solr to index about two million documents and query on it using standard
request handler. I disabled all cache. I found phrase query was substantially
slower than the usual query. The statistic I collected is as following. I was
doing the query on the one field only. content:(auto repair) 47
ms repeatablecontent:("auto repair") 937 ms
repeatablecontent:("auto repair"~10000) 766 ms repeatable What are the
factors affecting phrase query performance? How come the phrase query
content:("auto repair") is almost 20 times slower than content:(auto repair)? I
also notice a the phrase query with a slop is always faster than the one
without a slop. Is the difference I observe here a performance problem of
Lucene or Solr?
It will be appreciated if anyone can help
