# Start with Data

> Perform queries using text data that can be resumed to fetch additional results.

## Request

<ParamField body="data" type="string" required>
  The text data to be embedded and used for querying.
</ParamField>

<ParamField body="topK" type="number" default="10">
  The total number of the vectors that you want to receive as a query result.
  The response will be sorted based on the distance metric score, and at most
  `topK` many vectors will be returned.
</ParamField>

<ParamField body="includeMetadata" type="boolean" default="false">
  Whether to include the metadata of the vectors in the response, if any. It is
  recommended to set this to `true` to easily identify vectors.
</ParamField>

<ParamField body="includeVectors" type="boolean" default="false">
  Whether to include the vector values in the response. It is recommended to set
  this to `false` as the vector values can be quite big, and not needed most of
  the time.
</ParamField>

<ParamField body="includeData" type="boolean" default="false">
  Whether to include the data of the vectors in the response, if any.
</ParamField>

<ParamField body="filter" type="string" default="">
  [Metadata filter](/vector/features/filtering) to apply.
</ParamField>

<ParamField body="maxIdle" type="number">
  Maximum idle time for the resumable query in seconds.
</ParamField>

<ParamField body="weightingStrategy" type="string">
  For sparse vectors of sparse and hybrid indexes, specifies what kind of
  weighting strategy should be used while querying the matching non-zero
  dimension values of the query vector with the documents.

  If not provided, no weighting will be used.

  Only possible value is `IDF` (inverse document frequency).
</ParamField>

<ParamField body="fusionAlgorithm" type="string">
  Fusion algorithm to use while fusing scores
  from dense and sparse components of a hybrid index.

  If not provided, defaults to `RRF` (Reciprocal Rank Fusion).

  Other possible value is `DBSF` (Distribution-Based Score Fusion).
</ParamField>

<ParamField body="queryMode" type="string">
  Query mode for hybrid indexes with Upstash-hosted
  embedding models.

  Specifies whether to run the query in only the
  dense index, only the sparse index, or in both.

  If not provided, defaults to `HYBRID`.

  Possible values are `HYBRID`, `DENSE`, and `SPARSE`.
</ParamField>

## Path

<ParamField path="namespace" type="string" default="">
  The namespace to use. When no namespace is specified, the default namespace
  will be used.
</ParamField>

## Response

Same as Resumable Query.
