How the search works
Listings search can be crucial for your marketplace to thrive. Providing people with the right kind of search parameters and filters will help the users to easily find listings relevant to their needs.
In Flex listings are searched by using the /listings/query endpoint. This article approaches the search from two different prespectives: keywords and location. In addition to them other search parameters can be used to filter the search results in order to provide relevant search content. See the API reference documentation for a full list of search parameters.
The keyword search works so that it matches the
keywords parameter to
text content of a listing. The listing attributes that are matched in
keyword search by default are title and description. Listing public
data fields can also be used in the keyword search by defining them to
text in the marketplace's
listing public data schema.
text public data fields with defined schema are indexed for
When the listing text content is indexed, in addition to indexing the actual word, it is also broken into subwords, n-grams. For words longer than 3 characters, n-grams of 3 and more characters are constructed from the beginning and end of the word. So if an indexed field contains the word local in addition to the actual word the following n-grams are indexed: loc, loca, ocal, and cal.
The search results are sorted so that a match with an actual word from the listing always weighs more than a match with an n-gram. The order in which matches in different fields of a listing effect the search score is the following: title > description > public data fields. However, the search score differences between the fields are substantially smaller than the difference between a match with an actual word in the listing and an n-gram. Listings that don't match the search keywords at all are not included in the results.
keywords parameter is a single string that is tokenized on
non-alphanumeric characters. Therefore, passing local attractions as a
value for the parameter will conduct a search with two keywords: local
and attractions and those are then matched against the listing
content. A listing will be included in the results, in case any of the

the sorting of results. The bounds can then conviniently be used to
match search results to a map view.
