Hello,
On the solr wiki, here: http://wiki.apache.org/solr/SolrPerformanceFactors It is written: mergeFactor Tradeoffs High value merge factor (e.g., 25): Pro: Generally improves indexing speed Con: Less frequent merges, resulting in a collection with more index files which may slow searching Low value merge factor (e.g., 2): Pro: Smaller number of index files, which speeds up searching. Con: More segment merges slow down indexing. If I have a mergeFactor of 50 when I build the index and then I optimize the index, I end up with 1 index file so I have a small number of index files and having used mergeFactor of 50 won't slow searching? Or my supposition is wrong and the mergeFactor used when building the index has an impact on speed searching anyway? Thanks. ---------------------------------------------------------- This transmission is strictly confidential, possibly legally privileged, and intended solely for the addressee.
