Update search parameters for v0.29.0

[bidoubiwa]

Introduces optionalWords search parameter.
It lets you decide the search strategy for words matching during a search.

matchingStrategy gives you the possibility to chose how Meilisearch should handle the presence of multiple query words.

For example, if your query is Hello world by default Meilisearch returns documents containing either both Hello and world or documents that only contain hello. This is the last strategy, where words are stripped from the right.
The other strategy is all, where both hello and worlds must be present in a document for it to be returned.

import { instantMeiliSearch } from '@meilisearch/instant-meilisearch'

const searchClient = instantMeiliSearch(
  host,
  apiKey,
  {
      matchingStrategy: 'all' // default last
  }
)
