This article provides both visual and written instructions for searching Reveal data for keywords.
Entering a term in the Search Bar at the top of the Dashboard or any of its views will start a Keyword search. There are many options available and a few syntactical things to keep in mind.
- The Dashboard (which offers visualizations through the Dashboard, the Grid, Clusters or Communications) features the Search Bar in its top center.
- To begin a keyword search, enter a term in the Search Bar. We will start with a one-word example, raptor.
- If you simply press ENTER, this will be treated as a keyword search by default.
- You may select All documents with keyword raptor to set this as a keyword search.
- You may select Discover concepts about raptor to begin a Concept Search.
- All document counts, graphs, Filter lists and tables will update with results of the search, and the Results pane will open with document cards for the top items.
- The search may be refined with additional keywords or added Conditions (in Advanced Search) or Filters (from Filters in the Sidebar or as selected from bars in the Dashboard graphs).
- The search may also be enhanced with Concepts added under Add Conditions in Advanced Search or from a Clusters selection.
Keywords versus Concepts
- A Keyword is a word or phrase that directly matches material indexed in Project documents and when entered retrieves these documents.
- A Concept is a word or phrase that is parsed by Reveal to suggest other possibly related content found in the project. See How to Search Concepts for more information.
Phrases and Special Characters
- Keyword Phrases must be entered between quotation marks ("") in order to be treated as a phrase and not a collection of words.
- Concept Phrases are evaluated differently and may be entered without quotation marks.
- Keywords with special characters (e.g., "AT&T") must be entered between quotation marks ("") in order to be treated as a phrase and not a collection of legal and illegal characters.
- Proximity is expressed as <term1> w/# <term2>, for example ice w/2 soda.
- Wildcard search is currently limited to the asterisk (*), and will interpret * as zero or more characters.
- Negative: Reveal supports A AND NOT B, and A OR NOT B, but does not support A NOT B.
- Common words are treated differently in Reveal 11. Reveal 11 uses different Elasticsearch analyzers: instead of using the StopFilter to keep common words from being indexed, the CommonGramsFilter is used instead to support efficient searching of common words.
