Which part of the search query the pattern should match: - startsWith. The pattern must match the begginning of the query. - endsWith. The pattern must match the end of the query. - is. The pattern must match the query exactly. - contains. The pattern must match anywhere in the query. Empty queries are only allowed as pattern with anchoring: is.
Determines how the Exact ranking criterion is computed when the search query has only one word. - attribute. The Exact ranking criterion is 1 if the query word and attribute value are the same. For example, a search for "road" will match the value "road", but not "road trip". - none. The Exact ranking criterion is ignored on single-word searches. - word. The Exact ranking criterion is 1 if the query word is found in the attribute value. The query word must have at least 3 characters and must not be a stop word. Only exact matches will be highlighted, partial and prefix matches won't.
Determines if and how query words are interpreted as prefixes. By default, only the last query word is treated as prefix (prefixLast). To turn off prefix search, use prefixNone. Avoid prefixAll, which treats all query words as prefixes. This might lead to counterintuitive results and makes your search slower. For more information, see Prefix searching.
Strategy for removing words from the query when it doesn't return any results. This helps to avoid returning empty search results. - none. No words are removed when a query doesn't return results. - lastWords. Treat the last (then second to last, then third to last) word as optional, until there are results or at most 5 words have been removed. - firstWords. Treat the first (then second, then third) word as optional, until there are results or at most 5 words have been removed. - allOptional. Treat all words as optional. For more information, see Remove words to improve results.
Strategy for multiple search queries: - none. Run all queries. - stopIfEnoughMatches. Run the queries one by one, stopping as soon as a query matches at least the hitsPerPage number of results.
Order of facet values that aren't explicitly positioned with the order setting. - count. Order remaining facet values by decreasing count. The count is the number of matching records containing this facet value. - alpha. Sort facet values alphabetically. - hidden. Don't show facet values that aren't explicitly positioned.
min. Return matches with the lowest number of typos. For example, if you have matches without typos, only include those. But if there are no matches without typos (with 1 typo), include matches with 1 typo (2 typos). - strict. Return matches with the two lowest numbers of typos. With strict, the Typo ranking criterion is applied first in the ranking setting.
