- Both regular and irregular
CAT => CAT, CATSCHILDREN => CHILD, CHILDREN

Comparatives and Superlatives
What other word variations are automatically retrieved? • Comparatives and superlatives

“BOOK” “FINANCIAL FUTURES”“THE CAT IN THE HAT”
• TIP! Truncation can be used within quotation marks
“UNIVERSAL DESIGN*” =>
UNIVERSAL DESIGNUNIVERSAL DESIGNSUNIVERSAL DESIGNING
Truncation and Wildcards
Can I use truncation to find word variations? • Right, middle and left truncation are now all available!
- Any combination can be used
• Use * to retrieve 0-10 characters
- Use [*n] or $n to limit to a maximum number of characters (0-125)
- * can be used to replace a space
• Use ? to replace a specific number of characters
- Use to retrieve the exact number of characters
- ? cannot be used to replace a space
Truncation and Wildcards
Left and Right Truncation Examples• *TOXIC* – retrieves 0-10 characters at the beginning and/or end of a word
TOXIC, TOXICOLOGY, CYTOTOXICITY, INTOXICATED
• MONO[*15] or MONO$15 – retrieves up to fifteen trailing characters
MONORAIL, MONOTONOUS, MONOMETHYLARSONOUS
• ?????DERM – retrieves exactly leading characters
PACHYDERM but not EPIDERM, ECHINODERM,

• SUL[*2]UR retrieves up to two characters in the middle of a word
SULFUR, SULPHUR
Additional Search Tools
Additional Tools for Advanced Searching • Searching multiple terms and phrases
• Boolean / logical operators
• Proximity connectors
• Nesting
• Field indexing
• Look Up feature
Boolean Operators
Can I use Boolean (logical) operators?
AND Both / all terms must be present
OR Either term must be present
NOT Eliminates hits on the term after NOT operator
NOTE: AND is implied between terms separated by a space
CANCER RESEARCH = CANCER AND RESEARCH
Proximity Connectors
What proximity connectors are available? PRE/# => Exact order of termsP/#
• PRE/0 retrieves terms as a phrase but allows word variations
CANCER P/0 RESEARCH => Exact phrase, term variations
“CANCER RESEARCH” => Exact phrase, no term variations
• PRE/5 or P/5 allows up to 5 words to occur between search terms
CANCER PRE/5 RESEARCH => Up to 5 words between
Proximity Connectors
How should a search a hyphenated word?
TIP! A hyphen linking terms is equivalent to PRE/0 between terms
ULTRA-VIOLET is equivalent to ULTRA P/0 VIOLET
And will retrieve:
ULTRA-VIOLETULTRA VIOLETULTRA-VIOLETSULTRA VIOLETS
Recommended search to retrieve all variations:
ULTRAVIOLET OR ULTRA-VIOLET
ULTRAVIOLET OR ULTRA P/0 VIOLET
Proximity Connectors
What proximity connectors are available? NEAR/# => Any order of termsN/#
• NEAR/0 retrieves terms as a phrase (in any order) and allows word variations
CANCER NEAR/0 RESEARCH => Any order, term variations retrieved
• NEAR/25 or N/25 allows up to 25 words to occur between search terms
CANCER N/25 RESEARCH => Any order, up to 25 words between
Proximity Connectors
What proximity connectors are available?
LNK => Used to ink headings with subheadings or qualifiers inbiomedical databases
NOTE: LNK has numerous other database-specific applications.
EMB.EXACT(“ABDOMINAL CANCER” LNK “DIAGNOSIS”)
Searching Words and Terms
Are there words that aren’t searchable on ProQuest Dialog? • All words are searchable as free text terms on ProQuest Dialog including
AN, BY, FOR, FROM, OF, THE, TO, WITH
• TIP! ProQuest Dialog Boolean/Logical operators (AND, OR, NOT) and proximity connectors (PRE, NEAR, LNK) are searchable as words when enclosed in quotation marks
“AND” “PRE”
“OR” “NEAR”
“NOT” “LNK”
Nesting
Can I use nesting (parentheses) to group terms? • Yes, multiple layers of parentheses can be used
• Use parentheses to “nest” terms or change the order or processing
• Especially important when multiple operators are used!
((STRUCTURAL OR URBAN) NEAR/5 DESIGN) AND ((FLOOD OR LANDSLIDE) NOT (EARTHQUAKE OR TSUNAMI))
Field Indexing
Can I limit my search to specific fields? • Field codes are available
• Some standard fields are indexed in all databases
TI Title
AB Abstract
AU Author
PUB Publication Title
DTYPE Document Type
• Each database also has unique field codes based on data available and indexing
EMB Emtree subject headings (EMBASE)
Field Indexing
What is the syntax for limiting by field codes? • List the field code(s) first and enclose terms in parentheses
• “Stack” multiple field codes with commas
TI (CANCER RESEARCH)
TI,AB (AGRICULTUR* NEAR/3 FERTILIZ*)
PUB(“JOURNAL OF ECONOMICS”)
NOTE: Also retrieves
The Journal of Economics
Journal of Economics and Industry
PUB.EXACT(“JOURNAL OF ECONOMICS”)
Field Indexing
How can I identify the field codes available for each database? • Consult the list of standard fields in ProQuest help
• Other fields are database-specific
• Start with the drop-down menu in Advanced Search
• Field codes for major files listed in online HELP
