check_invalid_near_within_operators() → None

Check for invalid NEAR and WITHIN operators in the query. EBSCO does not support NEAR and WITHIN operators.

check_invalid_syntax() → None

Check for invalid syntax in the query string.

check_invalid_token_sequences() → None

Check for invalid token sequences based on token type and the previous token type.

check_unsupported_wildcards(query: Query) → None

Check for unsupported characters in the search string.

get_precedence(token: str) → int

Returns operator precedence for logical and proximity operators.

syntax_str_to_generic_field_set(field_value: str) → set

Translate a search field

validate_query_tree(query: Query) → None

Validate the query tree. This method is called after the query tree has been built.

validate_tokens(*, tokens: List[Token], query_str: str, field_general: str = '') → List[Token]

Pre-linting checks.
