Custom Query (2152 matches)

Reported by dread, 4 years ago.

Search of package name and title (and other fields) using regular expressions.

Current example use-case: Wanting to specify packages with title beginning with 'B'.

Issues:

• Syntax for specifying regex over natural language search - could it be contained in the q param so be available to users of the WUI, or do we simply make it alternative fields?

Implementation:

• Postgres reg ex searching detailed here:

New domain object: PackageRelationship? (revisioned)

Attributes:

• subject (Package reference)
• object (Package reference)
• type (string)
• comment

Relationship type values: depends_on (dependency_of) derives_from (has_derivation) child_of (parent_of)

Relationship type is stored as a string, as given in the first column. The reverse relationship (bracketed) is given just for display purposes only.

Subject / Object - as in a sentence: "Dracos is derived from OSM" is <subject> <predicate> <object>. We'll use 'type' instead of 'predicate' as that is a more familiar word.

WUI:

• View: show both sides of the relationship (but think carefully -- e.g. a given package may have *many* dependents ...)
