Stop Words
Xapian supports a stop word list, which allows you to specify what words should be removed from a query before processing. This list can be overridden or stop words can still be searched for if desired, but by default any words in the active stop words list will not be searched for.
Example
SEARCH /bank/
{
"_query": {
"personality": "these days are few and far between"
}
}We can look this individual document, the field personality do not include the entire phrase we look in the query that is because remove all the stop words and only use “days” for the query.
Searching of Stop Words
Stop words can be searched by using Love and Hate Modifiers
(by adding + to the desired stop word) or by using an empty set of stopwords
in the _stopwords keyword:
SEARCH /bank/
{
"_query": {
"personality": "+these days +are +few +and +far +between"
}
}The above example is equivalent to:
