Hi everyone,

I've got a bit of a head-scratcher here. I'm running Umbraco 10.4, although I was having the same issue in 10.3.2.

I have a document type called hazardPage, but some pages simply aren't appearing in the Examine/Lucene index. If I go to Examine Management and search for __NodeTypeAlias:hazardPage then some pages show up but others don't.

It doesn't matter whether I search the internal or external index. If I use the "global" search in the top-right of Umbraco and type the name of one of the missing pages, it doesn't show up.

Rebuilding the index hasn't helped, and resaving/publishing the problematic pages hasn't helped. I'm not sure what else to try. Any ideas?

Edit: I shut down the site, deleted the index, and let it rebuild. Then I noticed this entry in the log:

System.ArgumentException: Document contains at least one immense term in field="__Icon" (whose UTF8 encoding is longer than the max length 32766), all of which were skipped.  Please correct the analyzer to not produce such terms.  The prefix of the first immense term is: '[3c 3f 78 6d 6c 20 76 65 72 73 69 6f 6e 3d 22 31 2e 30 22 20 65 6e 63 6f 64 69 6e 67 3d 22]...'

I'm guessing __Icon is a system field (with the double underscores) so is there some way I can figure out which page is causing the issue?
