Caches don't really count here. You're not using filter queries so filterCache isn't germane. documentCache is only for holding the document read off disk, it probably isn't doing much in your example that would impact differences in search time unless you're returning massive numbers of documents. queryResultCache isn't getting re-used. Think of this as a list of document IDs keyed by the *entire* query. by making any changes to the query you're not going to use the cache. To understand this, consider that the clauses aren't really separate. Any additional clause could easily change the scoring of a document that matched both queries. So re-using the cache on a "by clause" basis wouldn't produce correct results. In other words, caches aren't going to help you here. > Second, > I have 5 or more phrase queries included wildcard per query such as "query1* > query2*"~2 OR "query3* query4*"~2 ... > In the worst case, phrase queries included wildcard in one query are more > than 30. > QTime is more than 60 second. > Can we see the results of attaching &debugQuery=on to the URL? your pseudo-code may well be hiding the issue. We don't know what query parser you're using. Wildcards aren't usually analyzed for phrase queries for instance, so on the face of it there's not much that can be said... Additionally, the field type and field definitions from your schema.xml would be helpful for the fields you're searching on.
