Do I have to look for maxBooleanClauses when using filters ?

One of the configuration variables we can find in the solrconfig.xml file is maxBooleanClauses, which specifies the maximum number of boolean clauses that can be combined in a single query. The question is, do I have to worry about it when using filters in Solr ? Let’s try to answer that question without getting into Lucene and Solr source code.

In the previous entry, we tried to cover what we saw at the first day of Lucene Eurocon 2011 conference. However, from our point of view, the second day was the more important one, due to the fact that this was the day we had our talk. But let’s start from the beginning.

Surely you noticed a decreased activity of solr.pl. But this is not related to preparations for winter sleep. We are not bored also. The reason is the hot period in relation to the project deadline, which we perform within our professional work. In addition, the rest of our free time is occupied by two subjects which are mentioned below.

Deep paging problem

Rafał Kuć Solr 18 July 201111 November 2020deep, deep paging, index, lucene, paging, solr 0 Comment

Imagine the following problem – we have an application that expects Solr to return the results sorted on the basis of some field. Those results will be than paged in the GUI. However, if the person using the GUI application immediately selects the tenth, twentieth, or fiftieth page of search results there is a problem – the wait time. Is there anything we can do about this? Yes, we can help Solr a bit.
