Query

Component description

The MKSearch query component is responsible for handling HTTP-based search queries by general users. It's implementation is currently in the form of a single HttpQuery servlet class that formulates queries via an SeRQLQueryBuilder, passes these to a file-based Sesame RDF repository and displays the results with a custom ResultsRenderer type.

Results cacheing

Standing RSS feeds and results paging will also require a result cache to optimise performance on the server side. However, the cache mechanism also needs to be integrated with the repository management interface, so that stale results are purged.

AND and AND NOT queries

The query builder should interpret the + and - symbols immediately before a word to mean AND and AND NOT respectively.
