 +===== Searching =====
 +{{thesaurus11.png?​200x100 }}To search for a name or title in the CERL Thesaurus, enter a search term into the search box and select the segments of the database you wish to search by ticking the boxes below the search box. You may search in more than one segment at a time. Searchable are name forms (in any word order), record identifiers (CT identifiers and other identifiers) as well as words and codes from the activity and geographic notes fields.
-==== Full text search ​==== +The records that match your search ​terms are grouped according ​the database segments they belong ​to. I.e. when searching ​for //​paris//, ​the capital of France will appear ​in the places section while Geneviève <de Paris> ​will appear ​in the persons section.
-{{ :​resources:​cerl_thesaurus:​editing:​search1.png?​300|Search}} +
-Probably ​the easiest approach ​to searching the CT is to use one or more terms in the full text search field. A full text search in the new environment ​will typically yield more hits than in the previous system, due to different indexing principles applied to the data. (To let your search mimic the behaviour of the old system, see below.)+
-As default your search result will be grouped the types of entities it contains: Corporate Names, Imprint Names, Places and Persons. Each group will display ​the first 25 hits and a link to the full set, if available. +Click on record to display the full information or click on the clipboard symbol to add that record ​to your [[#​clipboard|clipboard]] in order to consult it at a later point in time or download it.
-You may click a heading in these list to access ​the full record.+
-Clicking ​on "Show all ... records" ​will present the records of that set in a list that can be paged through using the buttons at the bottom of the page.+Clicking ​**More Search Options** opens an extended form from which you may select even more categories to search in(You may close this form by clicking "Fewer Search Options".)
-To bookmark a record, click the bookmark icon in the top right corner ​of the recordYou can access your bookmarked records from the item "​Bookmarks"​ in the top navigation bar.+The use of **Boolean search operators** is not supportedIf you enter more than one search term, the system will combine them by a logical //AND//. Phrase search is not supported either. For searching an exact name form, use the [[#​browsing|index browse lists]].
 +Right **Truncation** is possible by adding a question mark (**?**) to the search term.
-==== Limiting and sorting ​your search results ​====+You may **sort** ​your search results ​either alphabetically or chronologically. Please note that records without biographical dates will sort at the end of a set when chronological sorting is applied.
 +You may always **return to your last search result set** by clicking //Search// in the navigation bar on the right.
-If your search yields too many hits, you can reduce the size of your resultset using one of the limiting options in the right column of the result screen.  +===Examples ​of searching ​for names=== 
- +==(Personal or Imprint names)== 
-The option "​Search ​for names only" will limit your search to the headings and variant names fields of a record, thus emulating the search behaviour of the old CERL Thesaurus web interface. +**1.** Forms used as entry forms by one of the contributing libraries ​are indexed as they are, without any further additions etcFor example: 
- +<​code>​ 
-The limit "by feature"​ option allows you to select those records from the current sets that contain either provenance information,​ Links to the printers'​ devices or images (portraits). The number in parentheses indicates the size of the resultset after applying the limitation. You may also limit your result by the gender of the described person (persons and imprint names). +      ​1 budapest 
- +</​code>​ 
-The search results are by default sorted alphabetically. If you want to consult them in chronological order, you may do so by clicking "​chronologically (earliest first)"​ or "​chronologically (latest first)"​ from the "Sort your result"​ section below the Limit options. +or 
- +<​code>​ 
-==== Using search keys ==== +      ​1 ribalta,​ francisco 
- +</​code>​ 
-You may formulate more complex queries using the following search keys in the search boxA search key must always be followed ​by a colon and the value you are searching for without any blanks. You may also use parentheses and the Boolean operators AND, OR and NOT (note that the Boolean operators must be written in capital letters)+\\ 
- +**2.** Variant ​or fictional name forms are followed ​by an equals sign and the first (in alphabetical orderheading formFor example
-Truncation is possible by adding an asterisk (*) to the search term. To search for phrases, put those in quotation marks ("). +<​code>​
