No results for search in kibana

Elastic Stack Elasticsearch
1

hi,
I am getting no results for my search term "collectionaccount" in the field "tableId_lc" in Kibana. seems that for other docs all is working properly. not sure what am I missing:

"analysis" : {
"filter" : {
"autocomplete_filter" : {
"type" : "ngram",
"min_gram" : "3",
"max_gram" : "10"
}
},
"analyzer" : {
"autocomplete" : {
"filter" : [
"lowercase",
"autocomplete_filter"
],
"type" : "custom",
"tokenizer" : "standard"
}
}
},

field mapping:
"tableId_lc" : {
"type" : "text",
"analyzer" : "autocomplete",
"search_analyzer" : "standard"
},

I have doc with:
the following:
tableId_lc: collectionaccount

when I search the exact term "collectionaccount" (lucene) - I get no results.

any idea?

changing the max_gram to 40 seems to solve the problem.
