Table of Contents
| Name | Direction | Type | Default | Description |
|---|---|---|---|---|
| InvestigationName | Input | string | The name of the investigation to search for. | |
| Instrument | Input | string | The name of the instrument used in the investigation. | |
| RunRange | Input | string | The range of runs to search for related investigations. Must be in the format 0000-0000 or 0000:0000. | |
| StartDate | Input | string | The start date for the range of investigations to be searched. The format must be DD/MM/YYYY. | |
| EndDate | Input | string | The end date for the range of investigations to be searched. The format must be DD/MM/YYYY. | |
| Keywords | Input | string | A comma separated list of words to search for in the investigation. | |
| InvestigationId | Input | string | The ID of the investigation. | |
| InvestigatorSurname | Input | string | The surname of the investigator associated to the investigation. | |
| SampleName | Input | string | The name of the sample used in the investigation. | |
| DataFileName | Input | string | The name of the data file in the investigation. | |
| InvestigationType | Input | string | The type of the investigation. | |
| MyData | Input | boolean | False | If set to true, only search in investigations of which you are an investigator, e.g. ‘My Data’. |
| CountOnly | Input | boolean | False | Boolean option to perform COUNT search only. This is used for paging. |
| Limit | Input | number | 100 | The maximum amount of search results to return. Adds a LIMIT clause to the query. This is used for paging. |
| Offset | Input | number | 0 | The location to begin returning results from. This is used for paging. |
| Session | Input | string | The session information of the catalog search in. | |
| OutputWorkspace | Output | TableWorkspace | Mandatory | The name of the workspace that will be created to store the search results. |
| NumberOfSearchResults | Output | number | The number of search results returned for the INPUT. Performs a COUNT query to determine this. This is used for paging. |
This algorithm searches through the all active catalogs for investigations based on the parameters set, and saves the results into a workspace.
Example - searches for investigations in the catalog based on parameters set.
# When logging into the catalog the session class is returned.
# This can then be used throughout to perform other ICAT routines.
search_results = CatalogSearch(Instrument="ALF",limit=3)
# A tuple is returned from CatalogSearch(). The first item is the search results.
investigations = search_results[0]
print("The number of investigations returned was: {}".format(len(investigations)))
# Print the title of all returned investigations.
for investigation in investigations:
print("The title of the investigation is: {}".format(investigation['Title']))
# Log out of the catalog, otherwise results are appended to the workspace (search_results).
CatalogLogout()
Output:
The number of investigations returned was: 3
The title of the investigation is: CAL_ALF_14/02/2014 15:37:05
The title of the investigation is: CAL_ALF_18/11/2013 15:03:48
The title of the investigation is: CAL_ALF_19/11/2013 11:59:56
Example - paging results returned.
# When CountOnly is set to True a separate COUNT query is performed to see the total
# number of investigations that will be returned by this search. This is used for paging functionality.
# If CountOnly is not provided, then ALL results are returned. This can be extremely slow.
search_results = CatalogSearch(Instrument="ALF",CountOnly=True,StartDate="03/06/2012", EndDate="03/06/2014")
print("The number of search results returned was: {}".format(search_results[1]))
CatalogLogout()
Output:
The number of search results returned was: 109
