StrictDoc supports two search modes:

1. Text search: enter words or phrases to search across requirement/section fields and source file paths.
2. Query syntax: use the grammar-based query language for precise filtering.
   If the input contains query markers, StrictDoc parses it as a query and reports an error if parsing fails.

Text search syntax:

• foo bar matches like .*foo.*bar.* (ordered words with wildcard gaps).
• "foo bar" matches the exact phrase foo bar.

Query syntax rules:

• Every query component shall start with node..
• and and or expressions must be grouped using round brackets.
• Only double quotes are accepted for strings.

Examples:

node.is_requirement

Find all requirements.

node.is_section

Find all sections.

(node.is_requirement and "System" in node["TITLE"])

Find all requirements with a TITLE that equals to "System".

(node.is_requirement and node.is_root)

Find all root requirements.

(node.is_requirement and node.has_parent_requirements)

Find all requirements which have parent requirements.

See the User Guide's section "Query engine" for more details.
