Thanks for the suggestion. We increased the SORTSIG but this did not resolve our issue.
The truncation is also appearing in the raw suggest.json and when clicked on searches the truncated query. For example, "education and something that makes this really long" would cut off at "education and something that makes this rea" and the query would be "education and something that makes this rea"
However this only occurs for terms in the spelling-whitelist.cfg, longer terms that should have been picked up from the crawler don't even show up.
We have noted that in the Step-AnnieAPrimaryCollection.log there is a line that states ++Param: Maximum annnotation length: 42 but not sure if this is related, nor how to modify it?
