Example query

In this simple example we will find all witnesses of titles by Nasir al-Din al-Tusi.

Start

The tool starts with an option to select the first query step:

For the first step you can select one of two query types in the select box:

• "object type is" to select all objects of a type e.g. PERSON or WITNESS
• "object ID is" to select one object with a certain ISMI_ID e.g. 47316 for Tusi

Show all persons

If we select "object type is" in the first select box we get a second select box with all the possible object types like ALIAS, CODEX, COLLECTION and more.

In the second box we select "PERSON" which automatically runs a query to select all PERSON objects:

Under "Query result" we see that we have selected 2217 PERSON objects.

Because this are a lot of objects the system will not show all of the objects automatically. If you really want to see all 2217 objects you can click on the "show results" button but your browser may crash or take a while to display so many objects in a table.

Select persons by name

Now we want to narrow down the list of persons to only those that have "tusi" in their name.

For this we click on the "add step" button.

This gives us a second row of query steps with a query type select box.

In the first select box we select "Attribute (contains normalized)" to do a search that ignores diacritical marks in arabic transliterations.

Then we get a second select box with the names of all attributes we can search in and a text field for the text we want to search for.

Here we select the attribute "name_translit" in the second select box and type "tusi" in the text field and click on the "Submit" button.

This runs the query to narrow down the list of all persons to only those that have "tusi" in their transliterated name field:

Under "Query result" we see that now only 11 PERSON objects are selected.

Since this are not too many objects the selected persons are displayed automatically in a table below.

Above the table you can change how many results are shown on the page at a time ("Show XX results per page") and you can change which attributes of the object will be shown as columns of the table ("Columns: XX").

You can browse through the pages of the table by clicking on the "Next" and "Previous" buttons or by selecting one of the numbered pages in the pager element directly above the table.

In the table we find the row containing Abū Jaʿfar Naṣīr al-Dīn Muḥammad ibn Muḥammad ibn al-Ḥasan al-Ṭūsī and we note that the corresponding ismi_id is 47316.

Select objects by ID

Now we click "add step" again to add another step to select only Nasir al-Din al-Tusi to find only his works.

In the first select box we select "Object ID is" and we enter "47316" in the input field.

This runs the query to narrow down the list of persons to the one person with the ID 47316:
