Look up a BHSA feature: its gloss and valid values.

Validate and run a read-only MQL query; return the query and glossed results.

Only read-only queries (SELECT/GET) are accepted. Quoting rule (getting it wrong fails typechecking): enumeration features compare UNQUOTED (sp=verb, vs=nif); string features compare QUOTED (lex='BR>['). Verb lexemes carry a trailing '['. Call lookup_feature(name) to check a feature's kind/values.

Validate and run a Text-Fabric search template; return glossed results.

A template is one object per line, indentation = containment, constraints as unquoted feature=value pairs (sp=verb, lex=BR>[). Put the object you want results for on the LAST line. Call lookup_feature(name) to check a feature's values. Pinned to the BHSA 2021 release.

Convert a Text-Fabric search template to equivalent MQL for SHEBANQ.

Deterministic, no model involved: indentation becomes brackets, spaces become AND, string features get quoted from the catalogue. Use this to turn a notebook query into a citable SHEBANQ saved query. Templates using TF constructs beyond ' feature=value ...' lines are refused with an explanation. The mirror of to_tf_template.

Convert an Emdros MQL query to the equivalent Text-Fabric search template.

Deterministic, no model involved: brackets become indentation, AND becomes a space, quoted string values lose their quotes. GET clauses are dropped with a note (TF results expose all features). MQL using OR, NOT, FOCUS, or sequence operators is refused with an explanation. The mirror of to_citable_mql.

Answer a plain-language question about the Hebrew Bible.

With server-side translation enabled, returns generated MQL + results. On the public deploy (no server-side LLM) it returns a concise MQL-writing primer so you compose a read-only query yourself and call run_mql. Use the write-mql prompt for the full feature reference. The response also carries the query's Text-Fabric equivalent, derived deterministically from the MQL.
