-+ `vectorFilterMode` for pre-query or post-query filtering. For supported modes, see the [next section](#set-the-filter-mode).
++ `vectorFilterMode` to specify when the filter should be applied during the query. For supported modes, see the next section.

 In this example, the vector embedding targets the `contentVector` field, and the filter criteria apply to `category`, a filterable text field. Because the `preFilter` mode is used, the filter is applied before the search engine runs the query, so only documents in the `Databases` category are considered during the vector search.
