Service generates irrelevant PubMed feed

[const8ine]

The reason

When filtering PubMed API response, the service is limited in its ability to retrieve relevant publications. Relevance is determined by matching a theme and having a gene symbol present in the article title. In many cases, few articles are returned due to the lack of gene symbols in the titles of the articles. As a result, the number of articles retrieved is often much fewer than expected.

To Do

Implement a new algorithm to resolve a bug caused by incorrect logic.

DoD

1. A specific case is described to reproduce a bug.
2. An integration test is created using Jest.
3. New logic for retrieving relevant feed from PubMed API is implemented.
