Very fast SPARQL Engine, which can handle very large knowledge graphs like the complete Wikidata, offers context-sensitive autocompletion for SPARQL queries, and allows combination with text search. It's faster than engines like Blazegraph or Virtuoso, especially for queries involving large result sets.

Get `PrefilterExpression` from `SparqlExpression` #1613

Closed realHannes closed 1 week ago

realHannes commented 1 week ago

The SparqlExpression base class has been extended with the method getPrefilterExpressionForMetadata. This method constructs for suitable (logical) expressions which are used inside a FILTER a corresponding PrefilterExpression (see PR #1503). These PrefilterExpressions can be used to prefilter the blocks of an IndexScan by only looking at their metadata. At the moment, the following expressions provide an overriden implementation of getPrefilterExpressionForMetadata: strstarts (preliminary), logical-or and logical-and (binary), logical-not (unary) and the standard RelationalExpressions (<, ==, >, <=, >=).
