Search Features — Search Types

Searching Multiple Data Sources

  • dtSearch products support integrated relevancy ranking with highlighted hits across both online and offline data repositories.
  • Federated searching span any number of directories, emails (with nested attachments), and databases.
  • The Spider adds local and remote, static and dynamic online content to a search. The Spider can index sites to any level of depth, with support for public and private or secure online content, including log-ins and forms-based authentication.

Basic Search Types

  • Natural language searching lets you enter a “plain English” (or any other international language) unstructured search request.
  • Phrase searching finds phrases like: due process of law.
  • Boolean operators like and/or/not can join words and phrases: due process of law and not (equal protection or civil rights).
  • Proximity searching finds a word or phrase within “n” words of another word or phrase: apple pie w/38 peach cobbler.
  • Directed proximity searching finds a word or phrase “n” words before another word or phrase: apple pie pre/38 peach cobbler.
  • Phonic searching finds words that sound alike, like Smythe in a search for Smith.
  • Stemming finds variations on endings, like applies, applied, applying in a search for apply.
  • Numeric range searching finds any number between two numbers, such as between 6 and 36.
  • Macro capabilities make it easy to include frequently used items in a search request.
  • Wildcard support allows ? to hold a single letter place, and * to hold multiple letter places: apple* and not appl?sauce.
  • Regular expressions support provides a way to search for combinations of characters.
  • Digit character matching enables searching for patterns of numbers.
  • Unicode support allows for searching of all Unicode-based international languages, including support for “right to left” languages and special options for Asian character handling.
  • New multicolor hit-highlighting search options (up to 10 highlight colors)

Fuzzy Searching

  • Fuzzy searching uses a proprietary algorithm to find search terms even if they are misspelled.
  • Search fuzziness adjusts from 0 to 10 so you can fine-tune fuzziness to the level of OCR or typographical errors in your files.
  • A search for alphabet with a fuzziness of 1 would find alphaqet; with a fuzziness of 3, it would find both alphaqet and alpkaqet.
  • Fuzziness is not built into the index, so you can vary fuzziness at the time of each search.

Concept / Synonym / Thesaurus Searching

  • Concept searching lets you look for fast and find quick, speedy, etc.
  • dtSearch offers variable levels of automatic synonym expansion based on a comprehensive semantic network of the English language.
  • You can also add your own thesaurus terms.
  • For example, Frank and Jones would not be synonyms covered by the built-in semantic network.  But if you are working on the Frank Jones case, you may want to make them synonyms for purposes of your case.  The same principle applies to technical jargon like airbags and SRS.

The Smart Choice for Text Retrieval® since 1991
Search Tip #1:
In search requests containing two or more Boolean connectors (and, or, not, w/, pre/) use parentheses for grouping.
Without such clarification, Germany w/3 France or Italy could be either (Germany w/3 France) or Italy or Germany w/3 (France or Italy). Likewise, alphabet or noodle and not soup has a very different meaning as alphabet or (noodle and not soup) than (alphabet or noodle) and not soup. More


Search Tip #2:
In all searches, use quotation marks around phrases.
This tip is particularly important when a phrase includes one of the and, or, not Boolean connectors. For example, the phrase clear and convincing evidence includes the connector and. To search for the whole phrase as a phrase, use quotation marks: (“clear and convincing evidence” and not “preponderance of the evidence”) w/55 verdict.

Search Tip #3:
Activate fuzzy searching at a low level to sift through potential scanning and typographical errors.
This tip is important not only with OCR’ed text, but also with emails, where everyone mistypes.

Search Tip #4:
Some critical search setting are “built into” your index; check these out before starting.
For example, how you index emails will affect how you retrieve them in a search. For another example, with case and accent-sensitive indexing on, not only will your index size increase dramatically, but a search for Frank would miss both frank and FRANK. More
