In the above example, MultiFieldQueryParser is used like this:
query = MultiFieldQueryParser.parse("development", ["title",
"subject"],[MUST, MUST], SimpleAnalyzer())
And this is what I am doing in my project:
query = lucene.MultiFieldQueryParser.parse(command, ["Subject"], analyzer )
Where command is a string. Then I get an exception saying that Query object
is expected and str is given. Instead of doing as above if the do the
following then it works:
query = lucene.MultiFieldQueryParser.parse([command], ["Subject"], analyzer
)
And if I change the above as follows then I get an exception saying the
length of the first parameter and second parameter doesn't match.
query = MultiFieldQueryParser.parse([command], ["title", "subject"],[MUST,
MUST], SimpleAnalyzer())
This clearly states that the example above is not working in my case. Is
there anything I am missing?
Thanks a lot for your quick replies :),
