 After logging in, the main menu bar contains a grey ‘search’ box, which is retained throughout Skylark. This will perform a simple keyword search at any time during your Skylark session. Keyword searches will return matches from variable names or labels, and are not case sensitive. After logging in, the main menu bar contains a grey ‘search’ box, which is retained throughout Skylark.

-**N.B.** multi-term keyword searches are run as ‘exact phrase’ searches, e.g. if you wanted to search for //fish and chips// you must include that whole phraseyou couldn’t just type //fish chips// +\\  
 + 
 +**Keyword search parameters** 
 + 
 + The keyword search function has been updated in the latest Skylark release to be more intuitive and flexible. 
 +The default setting for a multi-term search is now an __implied OR search__. 
 +e.g. if you make a standard keyword search for //blood pressure// the results will be any variable with the word blood OR the word pressure in the variable name or label 
 + 
 +You can use the modifiers - + and “ next to one or more search terms to change the focus of a keyword search. 
 + 
 +^Modifier ^Use   ^Example                                                    ^ 
 +| **+**   |Inclusion   |//+blood +pressure// will find results with blood **and** pressure **anywhere** in the variable name or description| 
 +| **-**   |Exclusion       |//blood –pressure// will find results **including** blood but **excluding** pressure | 
 +| **"**   |Exact match      |//"blood pressure"// will find results with **both words next to** each other  | 
 + 
 + 
 +Combinations of the above multipliers can also be usede.g. //“blood pressure” –diastolic// will exclude all variables with diastolic in the description, from the “blood pressure” search results. 
 +\\ \\  
 +**N.B.** Please do not specify Boolean search terms e.g. AND, OR, NOT in a keyword search, as they will give many unexpected results!

-----+===Restricted Variables===
  
 +Due to restrictions placed on us by NHS Digital, we are unable to share certain restricted data outside of the Unit. These variables will not appear in any search results. Data restricted in this way includes:
 +
 +  * Mortality data
 +  * Cancer registrations
 +  * Hospital episodes (HES)
 +
 +If you think your project may require access to these kinds of data, __or__ other sensitive variables unavailable via Skylark due to a raised level of risk of reidentification to NSHD study members, please [[mrclha.swiftinfo@ucl.ac.uk|contact us]]. It may be possible for you to access these data from inside the Unit.
