Query Syntax

Archivum metadata search is powered by querexfuzz. The web Query page adds a small layer of input interpretation so common searches stay short while explicit queries remain available.

Live Interpretation

The Query page interprets input before sending it to the library query engine.

Input	Query sent to Archivum
`machine learning`	`# machine learning`
`!Wang`	`recent top 50 !Wang`
`year > 2020`	`recent top 50 year > 2020`
`title ~ /risk measure/`	`recent top 50 title ~ /risk measure/`
`q top 20 recent`	`top 20 recent`

Plain text with no querexfuzz symbols becomes a fuzzy # search. Text that contains one of #, ~, =, <, >, or ! is treated as an explicit query expression and wrapped in recent top 50. Prefix an expression with q to pass it through unchanged.

Querexfuzz Examples

Fuzzy search:

q # machine learning

Field matching:

q title ~ /credibility/ and year > 2019

Projection and ordering:

q select year, author, title author ~ /Wang, R/ order by -year

Limits:

q top 25 recent

Network Input

The Network screen uses a related but separate interpretation model:

Raw text is a raw query universe.
q ... is an explicit querexfuzz universe.
rg ... is a ripgrep full-text universe.
q ... rg ... combines a querexfuzz universe with a ripgrep filter.

Ripgrep Input

The Ripgrep screen does not reinterpret the search as querexfuzz. The typed text is the pattern passed to ripgrep. The live feedback line only checks whether the pattern compiles as regular expression syntax before the search is run.
