Does the OOTB AEM search use JCR scoring to display search results, which includes page visits, page updates and overtime it will display results based on that weight? I am trying to confirm if this is why certain search results do not displayed unless the users check the "exact match" box. 

When adding the internal search component and testing the search feature in AEM. We noticed not all search results are appearing as expected. Is there something that we missed when configuring the search function or any recommendations on how to fix the issue?
