aka. Did You Mean ReSearcher

Description

Sematext's DYM ReSearcher (DYMRS) is a Solr component that improves search experience by executing alternative queries when it detects that original queries produced poor results or no results at all due to spelling mistakes or typos in entered queries. It transparently returns alternative search results to the client. DYMRS exposes over half a dozen parameters that are specified in Solr's solrconfig.xml. These parameters control DYMRS's behavior: the heuristic for detecting bad queries and bad results, generation of alternative queries, selection of the best alternative result set, etc.

Do You Need It?

How do you determine if Sematext's DYM ReSearcher is for you?
  • You want to avoid users getting the "No Results Found" page.
  • You want to avoid users getting incorrect results just because they made a spelling error or a typo.
  • You want to avoid users getting too few or no results just because the exact query they entered produces no results.
