I am new to the Elastic stack, I want to do a specific search and it doesn't seem to work.
I want to search for a regex respecting word order.
For example this would be a query with query_string:
'(/Cytochrome[s]? P[-/ ]?450/)'
(Parameters are 'default_operator' : 'AND' and 'analyzer': 'keyword')
But this won't work because of the whitespace.
To make it work I have to change it like that
(/Cytochrome[s]?/ /P[-/ ]?450/) but this will search for the 2 terms to be present in my text and not as a single term.
The only way I found to preserve word order is to add
"" to the terms like that
'"(Cytochrome P450)"' but I am unable to use regex and the quotes is the same query...
"the protein Cytochromes P450 blabla" is correct and must match
"Cytochrome protein blabla, USP P-450 blabla" is not correct and must not match
Do you have a solution to make it work with my regex ?
Thanks for your replies.
