---------------------------
Summary: Multiple mlt.fl does not work well if the termvectors is
repeated
Key: SOLR-13106
URL: https://issues.apache.org/jira/browse/SOLR-13106
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: MoreLikeThis
Affects Versions: 5.5.6
Reporter: luyi
for an example：
my data is：
{ "id":"100079750",
"title":" "I like cat, don't like dog",
"tags":["cat"],
"desc":["my cat photo"]
}
by the way title and desc's Tokenizer is IK.
and filed tags' type is text_ws.
while using mlt.fl=title,tags,desc with parameters debugQuery
the result shows：
"interestingTerms":[ "desc:my",1.0, "desc:photo",1.0, "desc:don",1.0,
"title:dog",1.0, "desc:cat",1.0, "title:like",1.0],
"debug":{
"rawquerystring":"id:61",
"querystring":"id:61",
"parsedquery":"desc:my desc:photo desc:don title:dog desc:cat title:like",
"parsedquery_toString":"desc:my desc:photo desc:don title:dog desc:cat
title:like",
......
look at the word cat
it appears in field tags, desc and title,
but the result shows the word cat only used in field desc and was ignored in
field tags and title.
Finally, I found the reason when the word is repeated in more than one field.It
will only be used in one field to do the work.
otherwise sometimes word is only in field tags, but while doing the mlt, the
word was shows as other field such as title or desc, in fact there is never
appear in these fields!
