Add support for optional text constraints to FieldQuery
-------------------------------------------------------
Key: STANBOL-297
URL: https://issues.apache.org/jira/browse/STANBOL-297
Project: Stanbol
Issue Type: New Feature
Components: Entity Hub
Reporter: Rupert Westenthaler
Assignee: Rupert Westenthaler
Currently TextConstraint only supports a singe Text. The semantic is that
returned Entities must contain the whole text. This extension will allow to
explicit search for "Text1" OR "Text2".
Implementations are encouraged to boost the Rank of Results that contain
more/all of the optionally parsed texts.
This types of queries are planed to be used by the Taxonomy Engine to search
for Entities based on Chunks selected within the Text. Currently multiple
queries need to be executed by first searching for the whole Chunk and if no
results are found repeating the search with omitted Words.
