Improve Search functionality #31
Description
The current version of the search is not working too well, not only do we have a bug (see #24), also the results are also somewhat underwhelming.
It is difficult to really fix that and add a better search functionality.
Currently, we do only have 2 ways to search - one with and one without bif:contains.
Other tools give the user the choice of how to search.
E.g. Protege offers 5 options:
- contains
- startswith
- endwith
- exact match
- regex
Those match exactly the ways to search in SPARQL.
Probably we should also offer exactly those search functionalities.
