iFind is an SQL facility for performing text search operations. To use iFind you must define an iFind index for each column containing text that you wish to search. You can then search the text records using a standard SQL query with a WHERE clause containing iFind index syntax.

SQL Search index on JSON objects.

Hello there!
I am hoping to get some help with "SQL Search index" and JSON objects.
I am storing a JSON object in a column of type %Stream.GlobalCharacter
Property JSON As %Stream.GlobalCharacter;
I also have a index that looks like below.
Index AnalyticIdx On (JSON) As %iFind.Index.Analytic(INDEXOPTION = 0, LANGUAGE = "en", LOWER = 1);

I have an SQL text index defined like this

Index TextIndex On (Text) As %iFind.Index.Basic(IGNOREPUNCTUATION = 1, INDEXOPTION = 0, LANGUAGE = "en", LOWER = 1);

If I run a query like this:

SELECT
Text
FROM Post
WHERE %ID %FIND search_index("TextIndex",'ABC')

I get 20 results with posts containing the term ABC.

But each post can contain the term ABC several times.

Hi-

I have a SQL Query using %iFind.Highlight which returns text highlighting certain words and phrases. %iFind.Highlight seems to remove cr/lf from the returned text.

Here's my query

ClassMethod Search(pSessionId As %String, pSearchString As %String) As %String
{
set tTags="<span style='background-color:yellow;'>"
&sql(
SELECT %iFind.Highlight(Text , :pSearchString , , :tTags) into :results
FROM SSA_OCR.TempSearchable where sessionId = :pSessionId)
quit results
}

%iFind.Highlight

Hi

I've been working with SQL using an iFind index to search text. Using the %iFind.Highlight function in my SELECT statement I can get text back that highlights the found words using <b> and </b>

I am aware that using ##class(%iFind.Utils).Highlight, I can pass a parameter to override the <b> tag and use instead a <span> tag with style to change the background color of the found words.

Is there a way to override the <b> tag from a SQL statement?

Thanks

Hello All,

what is the best method for search a portion of text in a non-indexed global?

I need to implement an autocomplete kind of search, in a global of >1M registers (text type, not $lb)

Maybe the best way would be use a SQL mapped class, with 'Bitmap' indexes?

Thanks in advance!

iFind index missing data

I've been using iFind indices in one of my applications but this morning discovered that the index is missing data. I confirmed the issue also exists in our test environment and rebuilt the indices there. That seems to have fixed the immediate problem. However I'd like to understand how this came about to avoid it happening in the future.

Has anyone encountered this before and know the cause?

Hi,

I created an iKnow domain, where I supplied dictionaries, blacklist, metadata and stemming. The datasource is a table.

I would like to use iFind semantic search feature. It is said in the documentation that iFind use iKnow semantic analysis. But I want iFind to use the iKnow domain configuration I created earlier earlier. How can I do that ?

Regards,

Jack Abdo.
