Word delimiter filter - ignore words with hyphen

[Patrick Norwood]

Hi all,

I would really appreciate if anyone could navigate me, how I should set my
word_delimiter_filter to skip words containing hyphen? The desired result
is that the word with '-' in them, will be ignored by word delimiter filter.
One possible way that I tried to implement was using protected_words option
with regular expression - but I am not sure whether this is possible.
My settings for word_delimiter_filter are as follows:
:word_delimiter_filter => {
"type" => 'word_delimiter',
"preserve_original" => true,
"generate_number_parts" => false,
"split_on_case_change" => false,
"split_on_numerics" => false,
}

I tried adding this: "protected_words" => [/.*\-.*/] ...but it did not
work.

Is there any way to achieve this? Thanks in advance.

Patrick,

If I understand correctly, you just want to preserve the dashes as is and
not "word-delimit" on them. You can try something like this (I am just
preserving the - symbol: \\u002D):

"analysis": {
"analyzer": {
"wd1": {
"tokenizer": "whitespace",
"filter": [
"wd1"
]
}
},
"filter": {
"wd1": {
"type": "word_delimiter",
"type_table": [
"\\u002D => ALPHANUM"
]
}
}
}
