55 DATABASE INFORMATION

66 SFX FUNCTIONALITY Context-sensitive service, enabling you to access the document you require (possible from almost all DBs)  Link to the full text  Link to the library catalogue  Link to the table of contents of a journal  Link to an interlibrary loan service (ILL)

77 SEARCH STRATEGIES  Formulate the search query (type of information, topic)  Subject: general overview ↔ selected information? Initial (term) search in Wikipedia, encyclopaedias, including reference works Advanced search in subject databases  Synonyms, truncation, links, phrase search, alternative spellings, singular/plural forms, time coverage, etc.  The more precise the query, the more accurate the hits but, equally, the more often documents fall through the net  Document and save your search history!

88 SEARCH RULES I: BOOLEAN OPERATORS, PHRASE SEARCH AND Switzerland AND tourism - both terms must occur in the document (intersection) OR bicycle OR bike - at least one of the terms must occur in the document (union) NOT Asia NOT India - the document contains the first term but excludes the second (subset) SAME Clinton SAME Obama - both terms must occur within the same sentence NEARclimate NEAR/3 change – between both terms are zero to three other words ( ) Search order precedence: operators are weighted differently depending on the database, e.g. AND > OR > NOT – or the other way round! This weighting can be changed using brackets. Tip: Consult the Help pages! " " "hybrid car" - keeps terms together, or searches for them in the document in that exact order (phrase search)

99 SEARCH RULES II: TRUNCATION / WILDCARDS Truncation (T)NEBIS Recherche / Wissensporta l WoS Scopu s OVID SP LexisNexi s Pub Med Unlimited truncation calls up all the possible versions of the given word. From no characters to many. Example: “plantT" will find “plant" and “plants", “plantation”, “planting", etc. Limited truncation (n = number of characters) * not applicable with just one character *: or $ or * $ n ! to be placed before and/or after a root word * n * (Please note: Truncation in the multi-word search can lead to a phrase search!) The obligatory wildcard character is used for calling up specialised plural forms; it requires exactly ONE character to be present. Example: "dogT" will find "dogs", but not "dog"! ??# The optional wildcard character replaces ONE or NO characters. Example: "coloTr" finds results containing the words "color" or "colour" $ (only WoS) ? not applicable with just one character Tipp: Consult the Help pages! - often there is a context-specific Help function available (OVID SP, Web of Science, Scopus)
