Highlighting integer field
Hi,
Is it possible to highlight int (TrieLongField) or long (TrieLongField)
field in Solr?

I did not know about LUCENE-3080. (and take a look now)
So discussion seems to be beyond user mailing list, but thank you for your
information.

Hi again,
When I removed those lines from DefaultSolrHighlighter and rebuilt Solr it
seems to work.
final SchemaField schemaField = schema.getFieldOrNull(fieldName);
if (schemaField != null && ((schemaField.getType() instanceof
org.apache.solr.schema.TrieField)
|| (schemaField.getType() instanceof
org.apache.solr.schema.TrieDateField))) {
return;
}
There is still information about LUCENE-3080 in comments (and this JIRA
issue is still open) but some other issue seems to be resolved: SOLR-2497
which says it is blocked by LUCENE-3080.

Hi,
As Mike have pointed, there is no way to highlight numeric fields.
If you want to highlight, you have to index them as *text* field. It's not
about Solr, but Lucene.
(Maybe it's possible to "highlight" them in application layer, server side
program or client side JavaScript, rather than Solr?)

Hi,
Thanks for your response. Do you maybe have an idea how to handle integers
(even on low level - Lucene) in highlighter?

So the short answer to your original question is "no." Highlighting is
designed to find matches *within* a tokenized (text) field only. That
is difficult because text gets processed and there are all sorts of
complications, but for integers it should be pretty easy to match the
values in the document and those in the query in the client, ie without
help from Solr?

Hi,
Thanks for response. It is quite important to me for example to highlight
multivalued field with many int or long tokens.

Hi Pawel,
Essentially, highlighting is a feature to show "fragments of documents"
that matche user queries.
With that, he/she can find occurrence of their query in long documents and
can understand their results well.
For tint or tlong fields (or other non-text field types), "fragments"
usually have no meaning.
So, excuse me, I cannot understand your intent.
If you specify your need a little bit more, I or other fellows may be able
to help you.

Tomoko
