NReco.NLQuery
NReco.NLQuery provides a simple way to add search-based interface into your .NET app. It was specially designed for matching business entities in context of structured data (tabular data or database, OLAP cube, text indexes etc). This library is useful for: keyword-based filters for lists/grids, custom semantic search by database(s), search-driven analytics (reports by search), parse incoming messages by bots.

- handles relative date phrases like "yesterday", "last week", "last month", "last year", conditions "between", "more than", "less than", "age>18", ranges like "before", "after". Custom date-recognizer phrases may be easily added.
- supports matching in external indexes (say, Lucene or ElasticSearch).
- synonyms for better recognition results and ontology matching
- can helps users to form a query by providing autocomplete suggestions
- includes a component that automatically configures recognizer by a data table description.
