The mine action information collected and stored in IMSMA^NG is useless without the ability to find it and use it to make operational decisions. That’s why IMSMA^NG includes a robust data search mechanism that provides an easy-to-use interface for building and running searches. The IMSMA^NG search function has three primary purposes:

• to navigate to data
• to display data on the map
• to prepare data for reports and analysis

The navigation and map display searches are typically designed to find a single record or a set of records. These searches are generally simpler than the other kinds of searches and are designed to return records that users can browse through to find the necessary data.

The reporting searches are typically more complicated than navigation searches since they are intended to return a set of records to populate a report directly without any additional user interaction. These searches can also be saved and run independently of reports and used for browsing data.

Data quality analysis searches help identify possible data problems and ensure that mine action programme-specific workflow steps are being followed. These searches can be used to help protect data integrity.

In IMSMA^NG we refer to different types of functionality in the Search menu:

• simple as in only one filter option may be used
• advanced as in more than one filter option may be used and complex critera using AND / OR is possible to define
• saved searches which are prepared by information managers for usage by all users.

Saved searches simplifies the user experience and ensures consistency of use by sharing identical searches with all users. Of cause all users have the possibility to saved searches which is convenience way to re-use favourite searches.

Particularly, creating saved searches facilitate access to programme data and reporting is a key component of implementing and managing a mine action programme’s information workflow.

The IMSMA^NG version 6.0 database is pre-populated with saved searches developed by GICHD that may be customised to meet the specific needs of the mine action programme.

Simple Searches

The simple search options in the Search menu function exactly as all other filters in IMSMA^NG, see Search in the Using IMSMA portal.

Advanced Searches

The different types of search criteria e.g. subobject and geo area are described in Search in the Using IMSMA portal. The possibility to use AND / OR and intent the search parts (which correspond to brackets) makes the Advanced searches very flexible.

Using Prompt

When the prompt function is used in Advanced searches the re-usability and user-friendliness are greatly increased. For example, if a user wants to find all progress reports submitted by the "XYZ" organization and another user wants to have the same search but for the "ABC organisation, it better to save one search and prompt on Organisation.

SQL criteria

While the IMSMA^NG search functionality is extremely flexible allowing searches on CDFs, customised option list values and links among items, there are cases where users may want to run more complex searches that cannot be built using the Advanced search interface. For these cases, IMSMA^NG includes a special SQL search criteria that allows information managers to use a SQL query as filter criteria.

Creating searches using SQL criteria requires a detailed understanding of PostGreSQL's SQL syntax and the IMSMA^NG data model. Of cause your GICHD IM Advisor may support you in developing the SQL.

To use SQL criteria, simply provide a valid SQL statement in the following format:

SELECT [item_guid] FROM [item_table] WHERE...

The SQL query may be complex with left joins and subqueries but may only have one output column which should be the item_guid of the Search target i.e if your search target is Land then only output column should be hazard_guid.

We strongly recommended to develop and test the SQL query with a SQL tool before pasting it into the SQL criteria since IMSMANG does not provide SQL debugging support.

Saved Searches

Saving a search saves the criteria of the search rather than the search results. This means that searches are automatically updated when additional data is added to the system, ensuring that searches are returning results using the updated data.

Description Pre-populated Saved Searches

IMSMA^NG version 6.0 database is pre-populated with the following data quality Saved searches:

• 9 Saved searches that locates suspected duplicates
  • e.g "Victim Duplicate Name & Date Of Birth"
• 8 Saved searches that locates items without any geographical data
• 7 Saved searches that locates items that does not have any links to other items
  • e.g. "Assistance Without Links To Victim"
• 3 Saved Searches that locates item which are assigned to different locations
  • e.g. "Land & Activity Not Same Location"
• 3 Saved searches that have task as Search target
  • e.g. "Land Included In More Than One Task"
• 11 Saved searches that high-light possible mine action process quality issues
  • e.g. "Land Status Open with links to Activity or QM"
