Natural Language and Basic Search

• Divides up the question and discards the noise
  words
• Can I use aspirin to treat heart disease
• Elaborates (describing) the individual words and
  phrases
• treat therapy etc
• Searches for the subject groups separately and
  together
• Ranks the results
• Frequency of occurrence
• Proximity (words close together like adj6)
• Closeness to the words in the question
• 5 and 4 - all question concepts (like Boolean
  AND)
• 3 and below (at least one concept missing)

80
Basic Search and Ovid Advanced Search

• The purpose of Basic Search is to provide a
  reasonable number of highly relevant, ranked
  choices from the most recent part of the database
• The purpose of Ovid Advanced Search is to offer
  an interactive research type search across the
  entire selected database
• The results in Basic search are ranked but tend
  to offer a smaller number of broad references
• The results from Ovid Advanced Search offer the
  option to search the depth of the subject
  (explode) or be selective (subheadings), and so
  tend to be more precise
• You will often see around 500 results from a
  Basic Search but these will not all be 5 star
  results. A Basic Search is not like a traditional
  Ovid search result.

81
Multidatabase Searching

• Because the subjects are chosen from the OvidSP
  lexicon (rather than the different thesauri).
  They work equally across different databases.
• The number of results taken from each DB will be
  smaller because with more choices its easier to
  reach the target number of relevant records (500).

Full-Text Searching

• When you search full-text sources, you are
  searching every single word, rather than someone
  elses idea of what the publication is about.
• Advanced search is limited to exact match,
  unless truncation or synonyms are added.
