Fix search to only match whole words

sweep-ai[bot] commented 1 year ago

Description

This PR addresses the issue of the search functionality in the PublicationPageSearchMixin class in di_website/publications/mixins.py matching partial words. The current implementation is using the default analyzer, which results in undesired matches. To fix this, the code has been modified to use a new analyzer that tokenizes the text into individual terms, each term corresponding to a word. This ensures that the search only returns results that match the whole words.

Summary of Changes

Updated the index.SearchField in the PublicationPageSearchMixin class in di_website/publications/mixins.py to use a new analyzer.
Added an es_extra dict to the index.SearchField with the analyzer key set to the name of the new analyzer.
The new analyzer tokenizes the text into individual terms, each term corresponding to a word, ensuring that the search only matches whole words.

Please review and merge this PR. Thank you!
