Search query syntax¶
Exact phrase search¶
If a query is wrapped in
" (double quotes),
then only those results where the phrase is exactly matched will be returned.
Exact phrase search with slop value¶
~N (tilde N) after a phrase signifies slop amount.
It can be used to match words that are near one another.
* (asterisk) at the end of any term signifies a prefix query.
It returns the results containing the words with specific prefix.
~N after a word signifies edit distance (fuzziness).
This type of query is helpful when the exact spelling of the keyword is unknown.
It returns results that contain terms similar to the search term as measured by a Levenshtein edit distance.
Build complex queries¶
The search query syntaxes described in the previous sections can be used with one another to build complex queries.
