That's what I thought, but my experiments show differently. In actuality: I have a number of fields that are of type "text" (the default as it is packaged).
I have a type 'textCorrectlySpelled' that utilizes KeepWordFilterFactory in index-time analysis, using a file of terms which are known to be correctly spelled. I have a type 'textDictionary' that has no index-time analysis. I have the fields: <field name="CorrectlySpelledTerms" type="textCorrectlySpelled" indexed="false" stored="false" multiValued="true"/> <field name="TermsDictionary" type="textDictionary" indexed="true" stored="false" multiValued="true"/> I want 'TermsDictionary' to contain only those terms from some fields that are correctly spelled plus those terms from a couple other fields (CompanyName and ContactName) as is. I use several copyField directives as follows: <copyField source="Field1" dest="CorrectlySpelledTerms"/> <copyField source="Field2" dest="CorrectlySpelledTerms"/> <copyField source="Field3" dest="CorrectlySpelledTerms"/> <copyField source="Name" dest="TermsDictionary"/> <copyField source="Contact" dest="TermsDictionary"/> <copyField source ="CorrectlySpelledTerms" dest="TermsDictionary"/> If I query 'Field1' for a term that I know is misspelled (electical) it yields results. If I query 'TermsDictionary' for the same term it yields no results. It would seem by these results that 'TermsDictionary' only contains those terms with misspellings stripped as a results of the text analysis on the field 'CorrectlySpelledTerms'. Asked another way, I think you can see what I'm getting at: a source for the spellchecker that only contains correct spelled terms plus proper names; should I have gone about this in a different way? -----Original Message----- From: Stephen Duncan Jr [mailto:stephen.dun...@gmail.com] Sent: Monday, August 22, 2011 9:30 AM To: solr-user@lucene.apache.org Subject: Re: Text Analysis and copyField On Mon, Aug 22, 2011 at 9:25 AM, Herman Kiefus <herm...@angieslist.com> wrote: > Is my thinking correct? > > I have a field 'F1' of type 'T1' whose index time analysis employs the > StopFilterFactory. > > I also have a field 'F2' of type 'T2' whose index time analysis does NOT > employ the StopFilterFactory. > > There is a copyField directive source="F1" dest="F2" > > F2 will not contain any stop words because they were filtered out as F1 was > populated. > No, F2 will contain stop words. Copy fields does not process input through a chain, it sends the original content to each field and therefore analysis is totally independent. -- Stephen Duncan Jr www.stephenduncanjr.com
