Fuzzy searching can help find a word even if it is misspelled in the document. For example, a fuzzy search for "apple" will find "aqple" or "opple". Fuzzy searching can be useful when you are searching the Chemical Industry Archives, since all the documents are converted from scanned pictures using optical character recognition (OCR), which sometimes misinterprets letters, especially in some of the older documents.
Stemming extends a search to cover grammatical variations of a word. For example, a search for "fish" would also find "fishing". A search for "applied" would also find "applying", "applies", and "apply".
When I do a search, in what order are the documents displayed?
By default, the documents that match your search request are displayed by date, with the earliest document first. You may also choose to sort your documents by the number of "hits", or search term matches, that the document contains. In many cases, longer documents (which generally take longer to download) will contain more "hits" than shorter documents. However, just because a document contains more "hits" doesn't mean that it will contain more relevant, useful or interesting information.
