pub struct QueryLanguageParser { /* private fields */ }

Query language parser with schema awareness

Implementations

impl QueryLanguageParser

pub fn new( schema: Arc<Schema>, default_fields: Vec<Field>, tokenizers: Arc<TokenizerRegistry>, ) -> Self

pub fn with_router( schema: Arc<Schema>, default_fields: Vec<Field>, tokenizers: Arc<TokenizerRegistry>, router: QueryFieldRouter, ) -> Self

Create a parser with a query field router

pub fn set_router(&mut self, router: QueryFieldRouter)

Set the query field router

pub fn router(&self) -> Option<&QueryFieldRouter>

Get the query field router

pub fn parse(&self, query_str: &str) -> Result<Box<dyn Query>, String>

Parse a query string into a Query

Supports query language syntax (field:term, AND, OR, NOT, grouping) and plain text (tokenized and searched across default fields).

If a query field router is configured, the query is first checked against routing rules. If a rule matches:

• In exclusive mode: only the target field is queried with the substituted value
• In additional mode: both the target field and default fields are queried
