Hi folks!

I wanted to share FiltrES.js [https://github.com/abeisgreat/FiltrES.js](https://github.com/abeisgreat/FiltrES.js), a  
tool for compiling simple human readable expressions (i.e. '(height \<= 73 or  
(favorites.color == "green" and height != 73)) and firstname ~= "o.+")')  
into ES queries. This is useful for times when you want end users (or  
developers who aren't ES experts) to be able to query based on arbitrary  
filters. It doesn't use script filters, so it's safe and easy to use.

I'd love to get any thoughts/feedback as I am \*not \*an ES expert and  
FiltrES was written so I could use it, but I'm happy to expand it for more  
complex/interesting use cases.

Best,  
Abe

Cool stuff Abe.

Just a note, I think it’s a nice feature for developers but I’m more concerned with "end users".

A dev knows that == means equal but a end user will use field=x  
Same for different. != does not mean anything for a non developer.

My 2 cents.

Hi ,

How different is it from query\_string query langauge.  
Or is it using query\_string in the background.

Thanks  
Vineeth
