[Bug 28309] New: Searching with hyphen doesn't work with Elasticsearch
https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=28309 Bug ID: 28309 Summary: Searching with hyphen doesn't work with Elasticsearch Change sponsored?: --- Product: Koha Version: master Hardware: All OS: All Status: NEW Severity: normal Priority: P5 - low Component: Searching - Elasticsearch Assignee: koha-bugs@lists.koha-community.org Reporter: joonas.kylmala@helsinki.fi CC: nugged@gmail.com, stalkernoid@gmail.com If a biblio title contains the hyphen character "–" / \xE28093 and you try to search the title as it is written with the hyphen the search produces no results. I think we need to add hyphen to the list of punctuation characters to ignore to fix this problem. The file is in admin/searchengine/elasticsearch/index_config.yaml The issue could probably fixed also by removing hyphen in the tokenization step when storing the record to the index? -- You are receiving this mail because: You are the assignee for the bug.

Trying to search for a term like steam-boiler will return results where the term steam or boiler exists. In order to get correct search results add quotation marks "steam-boiler" to force Elastic Search to see it as a single term. Another example is to search for U-2 boats using U2 rather than U-2. U2 is a single term but it is not returning the expected results because U2 doesn't match "U-2" or U or a 2. One option is to add U2 to a 246 varying title tag so that it appears in search results. I think in this case Elastic Search is working the way it was designed. The question is should Koha make an exception to using the hyphen as a boolean operator? -- You are receiving this mail because: You are watching all bug changes.
