Lars Kotthoff commented on SOLR-556: ------------------------------------ I've applied SOLR-553 and confirmed that this problem is not fixed, regardless of the setting of usePhraseHighlighter. > Highlighting of multi-valued fields returns snippets which span multiple > different values > ----------------------------------------------------------------------------------------- > > Key: SOLR-556 > URL: https://issues.apache.org/jira/browse/SOLR-556 > Project: Solr > Issue Type: Bug > Components: highlighter > Affects Versions: 1.3 > Environment: Tomcat 5.5 > Reporter: Lars Kotthoff > Priority: Minor > Attachments: solr-highlight-multivalued.patch > > > When highlighting multi-valued fields, the highlighter sometimes returns > snippets which span multiple values, e.g. with values "foo" and "bar" and > search term "ba" the highlighter will create the snippet "foo<em>ba</em>r". > Furthermore it sometimes returns smaller snippets than it should, e.g. with > value "foobar" and search term "oo" it will create the snippet "<em>oo</em>" > regardless of hl.fragsize. > I have been unable to determine the real cause for this, or indeed what > actually goes on at all. To reproduce the problem, I've used the following > steps: > * create an index with multi-valued fields, one document should have at least > 3 values for these fields (in my case strings of length between 5 and 15 > Japanese characters -- as far as I can tell plain old ASCII should produce > the same effect though) > * search for part of a value in such a field with highlighting enabled, the > additional parameters I use are hl.fragsize=70, hl.requireFieldMatch=true, > hl.mergeContiguous=true (changing the parameters does not seem to have any > effect on the result though) > * highlighted snippets should show effects described above -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
