[v1.12.0] New index settings: `facetSearch` and `prefixSearch`

Following the changes related to Meilisearch v1.12.0 mega issue

Description

Add features introduced in Meilisearch v1.12.0: the facetSearch and prefixSearch index settings.

For more information refer to the docs:

• Facet search
• Prefix search

For reference, here is how these methods were implemented in JavaScript within meilisearch-js:

// get prefix search settings
const settings = await client.index('myIndex').getPrefixSearch()
// disable prefix search
await client.index('myIndex').updatePrefixSearch('disabled')
// reset prefix search settings
await client.index('myIndex').resetPrefixSearch()

// get facet search settings
const settings = await client.index('myIndex').getFacetSearch()
// disable facet search
await client.index('myIndex').updateFacetSearch(false)
// reset facet search settings
await client.index('myIndex').resetFacetSearch()

Implementation

Tasks:

• Add the relevant methods to configure facetSearch and prefixSearch index settings. (Note: facetSearch is partially available via updateGranularFilterableAttributesSettings)
• The methods associated with the /settings API route (to get, reset and update the settings globally) must be able to receive in the payload the new facetSearch and prefixSearch fields (in meilisearch-js, the equivalent methods are getSettings(), updateSettings(), and resetSettings())
• ⚠️ Add integration tests ⚠️
• Update the code samples in .code-samples.meilisearch.yaml to for the following keys, using the same example as their curl counterpart:
  • Add example for get_facet_search_settings_1
  • Add example for update_facet_search_settings_1
  • Add example for reset_facet_search_settings_1
  • Add example for get_prefix_search_settings_1
  • Add example for update_prefix_search_settings_1
  • Add example for reset_prefix_search_settings_1

Start by locating the Java client methods for index settings and the global /settings API, then inspect existing integration tests for comparable settings. Add get, update, and reset coverage for facetSearch and prefixSearch, update .code-samples.meilisearch.yaml with the six named examples, and run the integration tests to verify the new payloads and responses.
