I have indexed large pdf files into elastic search engine. I have analyzed this Unstructured Data with a snowball analyzer. this converts words like "running" to "run" using the snowball filter. but what if I want to search exactly for word "running" ?
I cannot go for using another field as these are larger files and can increase the index size in a larger extent.
So how can I use the snowball filter to use something like "preserver_original". so that I can have original word preserved along with the filtered word.
is there any way or alternative way to analyze the field as per my requirement??
