Tag search

[kaspiana]

Without tag searching, the tool is not very useful. It should be possible to search for documents with a limited query language based on tags and possibly file metadata like extension and ingestion date.

mage search vriska_serket terezi_pyrope # find all documents with both tags
mage search vriska_serket AND terezi_pyrope # ditto
mage search vriska_serket OR terezi_pyrope # find all documents with either tag
mage search (vriska_serket terezi_pyrope) OR june_egbert # find all documents with either both vrisska and terezi, or june

Search should also take into account tag relationships such as implication.

mage search human # find all documents with any tag which implies the human tag

Concerns:

• How to handle complex tag relationships when translating this query language to SQL?

Predicates:

• p (document has tag p)
• pre* / *post / pre*post (wildcard)
• p(n) / p(=n) (document has tag p with parameter equal to n)
• p(!=n)
• p(>n)
• p(>=n)
• p(<n)
• p(<=n)

Operators:

• x AND y / x y
• x OR y (inclusive)
• x XOR y (exclusive)
• ~x / -x (negation)
• (x y) OR z (grouping)
