Hi!
I have made an analyzer which gives me all trigrams of my input (as per
http://www.elastic.co/guide/en/elasticsearch/guide/current/ngrams-compound-words.html).
The thing is, I ALSO want all two letter words (and maybe also one letter
words) to be indexed.
So basically, the string "I like to write my programs in C" would yield:
- I
- lik
- ike
- to
- wri
- rit
- ite
- my
- pro
- rog
- ogr
- gra
- ram
- ams
- in
- c
Otherwise, it would be impossible to search for short words.
Is there any way to accomplish this?
I got a tip about using multi fields. But I want to search through the
entire document using a query string, and I don't know beforehand which
fields will exist. I currently do this via the _all field, but it didn't
seem like I could use analyzers for different parts of the _all field. Does
this mean I have to set "store":"yes" to all my fields? Or can I combine
query string with multi_match?
... It seems like I found the answer to some of the above questions just by
asking them.
{
"query": {
"query_string":{
"fields": [ "*" ],
"query": "2007",
"minimum_should_match": "-25%",
"lenient": true
}
}
}
When sending the above query to Elastic Search, it will crash if the query
does not resemble a date or time, even though lenient is set to true. Am I
doing something wrong?
Also, minimum_should_match seems to not be working as expected (or at least
as I expected) when using a non-negative number. With only two tokens and a
min match of 75%, results where only one token matches comes up. I could
explain in more detail. but maybe this one deserves its own question.
