# PrefixTermMatcher **`class PrefixTermMatcher`** prefix_match | Perform (phrase) prefix term matching on the specified fields, enforce phrase matching considering term-order (optionally) and phrase-slop. Can be also used as a simple implementation of typeahead functionality on text fields. **`pydantic model PluginConfig`** Fields - `fields (str)` - `in_order (bool | None)` - `min_token_length (int)` - `slop (int | None)` - `text (str | None)` **`PluginConfig.plugin_name: ClassVar[str] = 'prefix_match'`** Used to register and reference the plugin within a query. **`field PluginConfig.text: Optional[str] = ''`** Text to be used for fuzzy search **`field PluginConfig.in_order: Optional[bool] = True`** If text terms have to be matched in-order or not **`field PluginConfig.slop: Optional[int] = 1`** Specifies the amount of unrelated terms that are allowed to be found within the matched terms (phrase slop / term proximity). **`field PluginConfig.fields: str = 'body'`** Comma separated list of searchable fields **`field PluginConfig.min_token_length: int = 2`** Only query tokens which are longer than ‘min_token_length’ are considered for prefix matching
