Search

  • For details about the indexing methods used to search records see Indexing in EMu.
  • As many institutions that use EMu have extremely large databases, it may be necessary to limit a search to complete within a specified amount of time or to return no more than a specified number of records. To set the maximum search time and / or records retrieved see Searching options.
  • A detailed examination of EMu's support for Unicode, and how it impacts searching, is available in Support for Unicode.

There are many modules in EMu and each module has multiple pages and each page can have numerous fields. Fields can record text as well as multimedia (images, video, audio). EMu has a powerful search engine that can search across multiple fields and modules within one operation. Taking advantage of Boolean operators (AND, NOT, OR), wildcards (^, $, *,?), and a range of other special characters (@ for phonetic search; ~ for stemming, etc.) can greatly fine-tune your search.

EMu introduced full Unicode support with version 5.0. Unicode support greatly enhances searching in EMu, making it possible, for instance, to search for punctuation either as individual characters (?) or as part of a more complex string (fred@global.com).

If you are already familiar with searching in EMu, you will know that certain punctuation characters have a special meaning when used in a search. For example, searching for fre* in EMu 4.3 will find all words beginning with the letters fre. In EMu 5.0 onwards it is necessary to escape these special characters in order to have their special meaning applied. If the character is not escaped, the search will look for that character rather than applying its special meaning. A search for fre* in EMu 5.0 onwards will locate the four characters fre*.

Escaping a character involves preceding it with a backslash (\). Thus, to locate all words beginning with the letters fre in EMu 4.3, we'd search for fre*. To perform the same search in EMu 5.0, we'd search for fre\*.

Where support for Unicode alters the way a specific type of search is configured, details are provided in this documentation. For a comprehensive look at EMu's support for Unicode and the implications for searching, you may be interested in reading Support for Unicode.

By default, when a module is first opened it is in Search mode. Unless you are adding a new record, the first thing you'll probably want to do is search your existing records. With EMu it is possible to:

  • Run a search over multiple fields in a single operation.
  • Modify a previous search by adding or deleting search terms.
  • Perform an additional search and combine the results of this second (or third or nth) search with those of the previous search using one of the following relationships:

    Merge (OR)

    Intersect (AND)

    Subtract (NOT)

  • Nominate a Sort to be run automatically following a search.
