Simple Boolean Retrieval

[rahelarnold98]

Task Description

Cineast sported Boolean Retrieval with simple comparisons, as well as ranges (and for tags, which are ignored in this task). Therefore, this should - as generalised as possible - be introduced to vitrivr-engine.

The Boolean retrieval should support:

• [x] Comparison of literal values to (sub-fields) using common comparison operations (=, !=, >, <, >=, <=)
• [x] Support for different data types (numbers, strings, dates)
• [ ] Optional: Complex queries containing (AND, OR and NOT)

In practice, there are two major uses in a query pipeline, which probably need to be addressed differently:

• [x] Using Boolean queries as a data source in a Retriever
• [ ] Optional: Using Boolean queries to restrict a result set based on a boundary condition.

Dependencies

• None

Boundary Conditions

• Should work on sub-fields in a struct field.
• May require major changes to query definition language

Bump: Update description to capture Goal. Please feel free to add things to the list or clarify.

Update: A first iteration of boolean retrieval for sub-fields is open as a PR in #50

Closing issue. Moving optional requirements to separate ticket.
