Query LanguageThe text search engine allows queries to be formed from arbitrary Boolean expressions containing the keywords AND, OR, and NOT, and grouped with parentheses. For example: By typing information retrieval or typing information or retrieval you would find documents containing 'information' or 'retrieval' By typing information and retrieval you would find documents containing both information' and 'retrieval'
By typing web* you would find documents containing words starting with 'web' Fuzzy search Your Jewelry Connection provides fuzzy query support, where the system can generate words that are similar to the ones the user enters. The system supports simple MS DOS®-like wildcards and UNIX-like regular expression, matching against textual properties. Content queries support simple prefix matching, meaning that typing in the word "dog*" will return "dogmatic" and "doghouse." The system also provides linguistic stemming support that matches the various tenses of query words. So the word "swim" will expand to include "swimming," "swam," "swum," and other related words—this process is called inflection. Your Jewelry Connection performs this linguistic analysis of the words that are entered, as well as the reverse operation, called stemming. Fuzzy queries and stemming are available in all supported languages. Your Jewelry Connection allows query restrictions to be built by combining a number of "tests." Query restrictions available for use in any combination include: Searching for words and phrases. Searching for proximity of words or phrases to other words or phrases. Searching for words or phrases within textual properties. For example, searching for a word that appears in a document's abstract or summary. Searching for words or phrases within specific document types, such as within a Microsoft Excel spreadsheet or a Microsoft PowerPoint® presentation. Using parameters of <, <=, =, =>, > against a constant, such as a date or file size. Using Boolean operators, AND, OR, and AND NOT. Using wild cards, such as "*", "?" and regular expressions for "fuzzy" queries. Ranking by quality of the match. Your Jewelry Connection Inc. can search for both the author tag in Microsoft Office documents and the author "meta" tag in HTML files. Your Jewelry Connection understands all of Microsoft Office properties such as author, title, subject, summary, keywords, and any custom fields. These properties are also known as OLE document properties. For example, a user could search a server for all documents he or she wrote, if the location of that document had been forgotten. Similarly, a user who knew the author of a paper, but not its title, could search for papers written by that author.
