DataFrame.es_match(text: str, *, columns: Optional[Union[str, Sequence[str]]] = None, match_phrase: bool = False, must_not_match: bool = False, multi_match_type: Optional[str] = None, match_only_text_fields: bool = True, analyzer: Optional[str] = None, fuzziness: Optional[Union[int, str]] = None, **kwargs: Any) → DataFrame

Filters data with an Elasticsearch match, match_phrase, or multi_match query depending on the given parameters and columns.

Read more about Full-Text Queries in Elasticsearch

By default all fields of type ‘text’ within Elasticsearch are queried otherwise specific columns can be specified via the columns parameter or a single column can be filtered on with eland.Series.es_match()

All additional keyword arguments are passed in the body of the match query.

Parameters

text: str

String of text to search for

columns: str, List[str], optional

List of columns to search over. Defaults to all ‘text’ fields in Elasticsearch

match_phrase: bool, default False

If True will use match_phrase instead of match query which takes into account the order of the text parameter.

must_not_match: bool, default False

If True will apply a boolean NOT (~) to the query. Instead of requiring a match the query will require text to not match.

multi_match_type: str, optional

If given and matching against multiple columns will set the multi_match.type setting

match_only_text_fields: bool, default True

When True this function will raise an error if any non-text fields are queried to prevent fields that aren’t analyzed from not working properly. Set to False to ignore this preventative check.

analyzer: str, optional

Specify which analyzer to use for the match query

fuzziness: int, str, optional

Specify the fuzziness option for the match query

Returns

DataFrame

A filtered eland.DataFrame with the given match query
