match, which defaults to OR operator. For long search text such as:imos - satellite remote sensing - sst - l3s - multi sensor - 1 month - night time - australiaa record could score if
links.titleorsummaries.creditscontained any individual term. This produced many irrelevant results, including more than 5000 matches in the example above.With
