Search multiple indices

Sends multiple search request to one or more indices.

This can be useful in these cases:

• Different indices for different purposes, such as, one index for products, another one for marketing content.
• Multiple searches to the same index—for example, with different filters.

results.abTestID

integer

A/B test ID. This is only included in the response for indices that are part of an A/B test.

Required range: x > 1

results.aroundLatLng

string

Computed geographical location.

results.exhaustive

object

Whether certain properties of the search response are calculated exhaustive (exact) or approximated.

Show child attributes

results.exhaustive.facetsCount

boolean

Whether the facet count is exhaustive (true) or approximate (false). See the related discussion.

results.exhaustive.facetValues

boolean

The value is false if not all facet values are retrieved.

results.exhaustive.nbHits

boolean

Whether the nbHits is exhaustive (true) or approximate (false). When the query takes more than 50ms to be processed, the engine makes an approximation. This can happen when using complex filters on millions of records, when typo-tolerance was not exhaustive, or when enough hits have been retrieved (for example, after the engine finds 10,000 exact matches). nbHits is reported as non-exhaustive whenever an approximation is made, even if the approximation didn’t, in the end, impact the exhaustivity of the query.

results.exhaustive.rulesMatch

boolean

Rules matching exhaustivity. The value is false if rules were enable for this query, and could not be fully processed due a timeout. This is generally caused by the number of alternatives (such as typos) which is too large.

results.exhaustive.typo

boolean

Whether the typo search was exhaustive (true) or approximate (false). An approximation is done when the typo search query part takes more than 10% of the query budget (ie. 5ms by default) to be processed (this can happen when a lot of typo alternatives exist for the query). This field will not be included when typo-tolerance is entirely disabled.

results.exhaustiveFacetsCount

boolean

deprecated

See the facetsCount field of the exhaustive object in the response.

results.exhaustiveNbHits

boolean

deprecated

See the nbHits field of the exhaustive object in the response.
