SharePoint warns that "It may take several minutes for recently saved documents to appear in the search results." Sometimes, documents seem to be added almost immediately to the searchable list; at the other extreme, it may happen that no documents in a document libary ever end up being searchable. SharePoint provides no way for the ordinary user to control this behavior.
The following is HTML code for a simple form that allows the user to search for words in pages in a document library:
<form action="subweb url/_vti_script/search.idq" method="get">
<input type=hidden name=Template value="search">
<input type=hidden name=DocLibDir value="document library">
<input type=text name="SearchString">
<input type="submit" value="search">
For example, the following form allows you to search the "Shared Documents" document library for the 2004 Fall offering of this course:
SharePoint's search is extremely simple. Some obvious stopwords (such as the) are ignored. Other words are apparently just ored together; boolean operators are not recognized. Results seem to be ranked on the basis of frequency of matches within pages (not on the number of different words matched).
