Bug: The tab-delimited import logic in load_multi_search looks for a Url column, but the export creates a URL column, causing URL data to be lost on import.
_{Severity: HIGH}

🔍 Detailed Analysis

Exporting citations to a tab-delimited file via write_citations_app creates a column named URL. When this file is re-imported using load_multi_search with method="txt", the import logic attempts to find and rename a column named Url (mixed case) to url (lowercase). Due to case sensitivity, the URL column is not found and is not renamed. Consequently, a new, empty url column is created, and the original URL data from the URL column is lost. This breaks the round-trip data integrity for tab-delimited files.

💡 Suggested Fix

Modify the name_map in load_multi_search to handle the uppercase URL column name. For example, change the mapping from "Url" = "url" to "URL" = "url" to match the column name produced by the export function.

Potential issue: Exporting citations to a tab-delimited file via `write_citations_app`
creates a column named `URL`. When this file is re-imported using `load_multi_search`
with `method="txt"`, the import logic attempts to find and rename a column named `Url`
(mixed case) to `url` (lowercase). Due to case sensitivity, the `URL` column is not
found and is not renamed. Consequently, a new, empty `url` column is created, and the
original URL data from the `URL` column is lost. This breaks the round-trip data
integrity for tab-delimited files.
