Hi,
I created a webpages index using Nutch-0.9, while indexing I added a
field named *s3-type* in each document.
At the time of searching, I'm able to see the same field name and
related value in each hit retreived but the issue
is that when I try to call addRequiredField to the query, it throws
error (at runtime) that field s3-type is not a known field.
Here is the code for adding the field at indexing time (in a plugin
extended from IndexingFilter):-
doc.add(new Field("s3-type", "some value", Field.Store.YES,
Field.Index.TOKENIZED));
This is the code during searching (when I try to add a field as required
field to query):-
Query newQuery = Query.parse("dummy query", <conf object here>);
newQuery.addRequiredTerm("value", "s3-type");
Hits hits = <index searcher obj here>.search(newQuery, 300, null,
null, false);
I'm able to search properly for all normal queries, the problem comes
only when I try to do addRequiredTerm
Basically I need to filter the results based on a particular field
(s3-type in this case).
Query.parse() needs to know in advance about all fields supported by the
query, so that the field names are not treated as ordinary tokens. You
do this by declaring supported fields in query plugins' plugin.xml
descriptors. See how it's done in other query plugins.
