Hi there,

my question is about Word Delimiter Filter and if it can generate tokens  
according to the requirements I have.

Suppose my original text is "one\_twoThree\_four". I want to be able to match  
on "one", "two", "three", "four", and "twothree".

It seems to me that with Word Delimiter Filter I have a choice between  
generating either the tokens "two" and "three", or "twothree" (with  
generate\_word\_parts=false), but that I cannot get both of them. I thought  
that catenate\_words=true might solve my problem but it seems to have no  
effect on tokens generated by split\_on\_case\_change=true. Here are my  
settings:

"my\_worddelimiter\_filter" : {  
"type" : "word\_delimiter",  
"catenate\_all" : false,  
"catenate\_numbers" : false,  
"catenate\_words" : true,  
"generate\_word\_parts" : true,  
"generate\_number\_parts" : true,  
"preserve\_original" : true,  
"split\_on\_case\_change" : true,  
"split\_on\_numerics" : true,  
"stem\_english\_possessive" : true  
}

Can anyone help me out how to reach the desired behavior?

-Patrick
