Why might a 'Full Population' be necessary when updating an index?

A 'Full Population' is necessary when updating an index for several reasons, all of which can contribute to the overall integrity and effectiveness of search functionality within a database.

When there are new documents that introduce new concepts, conducting a 'Full Population' ensures that these new materials are fully integrated into the index. This means that any search queries can retrieve relevant results that encompass the latest information and ideas present in those new documents, maintaining the relevance of search outcomes.

Updating noise words, which are common terms often ignored in search queries, is another vital reason for performing a 'Full Population.' Adjusting these terms allows the indexing system to function more effectively, ensuring that searches yield high-quality results by filtering out terms that do not add significant value.

Additionally, when the extracted text is updated, a 'Full Population' ensures that any modifications to the content are reflected accurately in the index. This is crucial for maintaining the accuracy of search results, as outdated or incorrect information could lead to misunderstandings or misinterpretations of the data.

By encompassing all of these aspects—new documents, noise word updates, and extracted text modifications—a 'Full Population' guarantees that the index remains comprehensive, current, and capable of providing users with pertinent results. This holistic approach is
