public class Query
extends java.lang.Object
For example, the following query will search for documents where
the tokens 'good' and 'story' occur in some fields,
returns up to 20 results including the fields 'author' and 'date-sent'
as well as snippeted fields 'subject' and 'body'. The results
are sorted by 'author' in descending order, getting the next 20 results
from the responseCursor in the previously returned results, giving
back a single cursor in the
Results
to get the next
batch of results after this.
QueryOptions options = QueryOptions.newBuilder() .setLimit(20) .setFieldsToSnippet("subject", "body") .setScorer(CustomScorer.newBuilder() .addSortExpression(SortExpression.newBuilder() .setExpression("author") .setDirection(SortDirection.DESCENDING) .setDefaultValue(""))) .setCursor(responseCursor) .build(); Query query = Query.newBuilder() .setOptions(options) .build("good story");
