Is there an index analyzer setting to:

1. Treat diacritic letters (in my case polish diacritic letters ą, ć,  
ę, ł, ń, ó, ś, ź, ż) as US alphabet equivalents during search:  
ą -\> a  
ć -\> c  
..

What I mean is when I do search with pattern 'abc' i want to see in  
results 'abc' as well as 'ąbc', but when I search for 'ąbc' I want ES  
to find only 'ąbc'

This settings do not work, I expected asciifolding might be doing the  
trick:

index.analysis.analyzer.default.type: standard  
index.analysis.analyzer.default.stopwords: _none_  
index.analysis.analyzer.default.tokenizer: standard  
index.analysis.analyzer.default.filter: [standard, lowercase, stop,  
asciifolding, porter\_stem]

ES 18.7

Cheers!  
Michal

Are you sure you are using a query that also analyzes the search text? (query\_string, field, text)? If so, can you gist a recreation ([Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/help))?
