Hello
I'm trying to use Swedish stemming in elasticsearch and I keep getting
problem with it. I could need some advice about how to deal with this stuff.
The main problem is that the stemmers stems some words in a weird way which
makes my hits either go through the roof or not match at all.
At first I used the "Swedish" snowball filter but it seemed to stem a bit
"too hard".
Example:
Original =\> Stemmed
"ledare" =\> "led"
"ledig" =\> "led"
"ledighet" =\> "led"
"ledighetens" =\> "led"
None of these words should really be stemmed to "led". So, I changed to the
"light\_swedish" filter instead. It seems to be a bit more conservative with
its stemming which I like:
Original =\> Stemmed
"ledare" =\> "led"
"ledig" =\> "ledig"
"ledighet" =\> "ledig"
"ledighetens" =\> "ledig"
But, with other words it does a not so good job:
Original =\> Stemmed
"förmån" =\> "förma"
"förmåner" =\> "förmån"
"förmånen" =\> "förmån"
...
All of these should be stemmed to "förmån".
I get that the stemmers are not perfect, but how can I make the best of it?
How do you handle things like this?

in the example they use only "swedish"
