Planning the Search Topic The population of the world is aging. Many people are trying to improve their longevity and quality of life with controversial medical treatments and dietary supplements. One such treatment is the taking of hormone supplements to combat the effects of aging. Find articles written for the layperson that discuss the use of hormones in anti-aging therapies. 4

Planning the Search – Proximity Connectors Step 3: Use proximity connectors • Stop words

Planning the Search – Proximity Connectors Step 3: Use proximity connectors • Stop words – Not searchable on Dialog – Stop words are: AND, BY, TO, FROM, OF, WITH, AN, FOR, THE – Proximity connectors can take the place of stop words • Search phrases • Replace internal punctuation • Specify order and adjacency of search terms 9

Planning the Search – Proximity Connectors WITH (W) Words must be adjacent and in

Planning the Search – Proximity Connectors WITH (W) Words must be adjacent and in the order specified Note: you may omit the W and just use the parentheses () Examples: S bugs(w)bunny S bugs()bunny Both retrieve Bugs Bunny (DIALOG is not case sensitive) (W#) Up to X-number of words in between search terms, in the same order Example: S asthma(5 w)therapy? Retrieves: asthma can be treated with therapy 10

Planning the Search – Proximity Connectors NEAR (N) Words must be adjacent but can

Planning the Search – Proximity Connectors NEAR (N) Words must be adjacent but can be in any order Example: S game? (n)board? Retrieves: game boards or board games (N#) Up to X-number of words in between search terms, in any order Example: S asthma? (4 n)therapy? Retrieves: therapy in stable, chronic asthmatic patients or asthma can be treated with therapy 11

Planning the Search – Proximity Connectors SAME (S) Use (S) to restrict words to

Planning the Search – Proximity Connectors SAME (S) Use (S) to restrict words to the same paragraph or subfield LINK (L) Use (L) to link headings and subheadings in the descriptor field Example: aspirin(L)adverse effects 12

Planning the Search – Proximity Connectors 13 Connector Example Searches (W) real(w)estate real estate

Planning the Search – Proximity Connectors 13 Connector Example Searches (W) real(w)estate real estate (N) fiber? (n)optic? fiber optics optical fibers (#W), (#N) cost(1 n)living gone(2 w)wind cost of living gone with the wind (S) solar(s)heat solar in the same paragraph with heat

Planning the Search – Logical Operators Step 4: Use logical operators • Logical operators

Planning the Search – Logical Operators Step 4: Use logical operators • Logical operators link concepts (Boolean) • AND – connects concepts when both or all must be present – telecommut? and productivit? – market(5 n)share and tennis(w)equipment • OR – groups synonymous terms when at least one must be present – cat or feline – ultraviolet or uv or ultra(w)violet – Remember: “OR IS MORE” 14

Conducting the Search – Basic Commands • BEGIN – enter a database – Begin

Conducting the Search – Basic Commands • BEGIN – enter a database – Begin 47 – B 9, 16, 148 • SELECT – choose search terms – Select jury – S merge or acqui? • TYPE – display records • DISPLAY SETS – show search history – DS • LOGOFF – disconnects from Dialog and displays a cost estimate of the search session 16

Displaying Results – The TYPE Command Set Number s 1 Format / 6 Range

Displaying Results – The TYPE Command Set Number s 1 Format / 6 Range of Records / Examples: t s 1/6/1 -3, 5, 10 t s 2/3/all 17 1 -3

Displaying Results – Formats • Selected Format Options – – – Format 6 or FREE – titles Format 8 or SHORT – titles and descriptors Format 3 or MEDIUM – bibliographic Format 9 or FULL – complete record Format K or KWIC – keywords in context of the article • Check the Bluesheet formats for each database 18

Putting the Search Together • Building blocks: step by step, then combine all sets

Putting the Search Together • Building blocks: step by step, then combine all sets together ? s threat or hazard ? s radon or asbestos ? s s 1 and s 2 • Nesting: all search terms in one statement ? s (threat or hazard) and (radon or asbestos) • Both achieve the same result – Building blocks gives you more flexibility. – Nesting is shorter but leaves little room for error. Useful if you plan to save the search strategy to run again later. 19

Planning and Conducting the Search Summary • Use synonyms to identify alternate search terms

Planning and Conducting the Search Summary • Use synonyms to identify alternate search terms • Employ truncation to search for words that may have different endings • Use proximity connectors to connect words • Use logical operators (AND, OR) to link search terms together • Put the search strategy together • View records by using the appropriate format • TYPE and/or SAVE the results (PRINT for commercial accounts) 22

Modifying and Enhancing a Search – Basic Index • Basic Index – Search subject-related

Modifying and Enhancing a Search – Basic Index • Basic Index – Search subject-related information – Use a suffix to limit the search to a particular field. – Common suffixes: • /ti s skin/ti Searches title field s skin(n)cancer/ti • /de s melanoma/de Searches descriptor field s human(2 w)hormone? /ti, de • /co s oracle/co Searches company name s s 1/co field • /lp s global()warming/lp Searches lead paragraph 23

Basic Index • Basic index fields are word-indexed – Each word is searched as

Basic Index • Basic index fields are word-indexed – Each word is searched as a separate term – To search phrases, use proximity connectors – Remember to replace embedded punctuation with a proximity connector • Examples: – global(w)warming – wal()mart 24

Modifying and Enhancing a Search – Additional Indexes • Additional Indexes – Non-subject related

Modifying and Enhancing a Search – Additional Indexes • Additional Indexes – Non-subject related information – Use two-character codes before the search term (PY=) – Common Prefixes: • PY=publication year s py=2007 s py=2005: 2007 • PD=publication date s pd=20070110 • AU=author name s au=koop, c? s au=bowen, ezra • JN=journal name s jn=popular mechanics s jn=newsweek 25

Additional Indexes • Most fields are phrase-indexed • Must enter search term exactly as

Additional Indexes • Most fields are phrase-indexed • Must enter search term exactly as listed in the database – Do not use proximity connectors • Use EXPAND to verify correct spelling 26

Modifying and Enhancing a Search – Using EXPAND The EXPAND Command • Use EXPAND

Modifying and Enhancing a Search – Using EXPAND The EXPAND Command • Use EXPAND to verify spelling and view alphabetically similar entries • Index shows how a name is listed and the number of records that contain the name • Step 1: EXPAND using prefix + name – Example: e au=perls • Step 2: SELECT E numbers – Example: s e 3: e 6 s e 3 or e 7 27

Modifying and Enhancing a Search – Using EXPAND ? e au=perls t Ref E
