The new search interfaces developed for the DB-ALM revised version offer the following updated functionalities:
Two different options for progressive incremental query construction, based on controlled vocabularies and classification list, are offered for each data sector (the search interfaces are now made available for the methods data sector first, others will follow soon): Free text search and Guided search.
Free text search scans the entire content of all documents including titles and classification terms in a given data sector. It offers two search modalities: Auto-complete modus and Boolean operators.
AND/Single Space operators are used to retrieve documents which contain both of the specified search terms anywhere in the text (only one of these terms is not sufficient), but their behaviour is slightly different.
Single Space between words represents an AND operator, but both terms have to appear one after the other in the document.
For example: "aggregate culture" will retrieve documents where this specific experimental system is mentioned and not those documents where " aggregate" and "culture" do not occur together.
OR is used to retrieve documents which contain either the first or the second or both search terms anywhere in the text.
For example: chicken OR bovine means to find all documents that contain at least one of these terms.
NOT is used to retrieve documents which contain the first - but not the second - search term.
For example: the combination eye NOT bovine will exclude all documents that mention bovine; in this example it means to find all documents that study eye but bovine eye.
The wildcard character * substitutes for one or more characters. It can be used at the beginning and/or at the end of a word.
For example: if you enter *cultur*, the search engine will first search for the exact word "cultur" followed by a search for all word containing "cultur" in an automatic manner and, thus, would find cultur(es), cultur(ed) as well as (co-)cultur(e).
If you insert a search term without the use of a * wildcard, the system will give you all documents containing just this specific term. For example: culture means to retrieve all documents that contain precisely this term and would not find e.g. culture(s).
Guided search allows to construct customised and more specific queries by selecting and combining pre-determined search parameters which include e.g.: Method Name, Topics, Models & Strategies, Area of Concern, Biological Endpoints, Experimental Systems, Status. This data retrieval option offers the Auto-complete search modality that is activated whilst typing a keyword into the relevant search fields. It assists the user to easily identify a desired search term from a displayed drop-down list of suggestions.
Guided search cannot be combined with Free text search and for the very specific queries the first is recommended. The more parameters are selected in the Guided search modality, the more accurate and precise the search results are.
For example: search expression using the Guided search modality in the Methods data sector, designed to retrieve information on scientifically validated test methods for eye irritation, with bovine eyes as experimental model.
|Models & Strategies||Eye & Eye parts||20|
|Methods Status||Scientifically validated||2|
For example: wrong search expression using the Guided search modality in the Methods data sector. The result of the Method name search is already very specific and it is not relevant in combination with the second search term.
|Method Name||stem cell||2|
* The numbers represent the outcome of a retrieval procedure carried out by adding subsequent search parameters. The search was done in June 2015. The actual outcome is a subject to variation due to continuous database updates.
