    Adding a word to a single word search in PCI returns more results

    • Product: Primo
    • Product Version: All versions
    • Relevant for Installation Type: All types

     

    Symptom:


    When adding a word to the search, Primo returns more results


    For example:

    • Searching for one word return less results in comparison to searching for two (or more) words

    Example:

     

    Searching for documentary returns 21,473 records

    Searching for documentary film returns 24,102 records

     

    Explanation:

     

    Primo's search engine has a sophisticated algorithm which expands and alters queries so that the results returned will be relevant to the search.

     

    The search engine algorithm builds a series of Boolean searches which increases the relevance of the results, as opposed to an SQL search, for instance, which works in a direct manner on the data.

     

    Among them is searching in full text of PCI records. Searching a single term in PCI's full text will , due to its sheer size, would return an extremely large amount of records, all meeting the search query but  many of them may have low relevance to the end user

     

    Conclusion:

     

    The results of different searches aren't necessarily comparable in a linear relation
