Searching with multiple key words

[bees]

Hi, I'm building an app that will eventually be a searchable databse of undergraduate theses. At the moment I'm using the template provided by powerapps which is actually very similar to the style of databse I had envisaged. 

I'm having an issue with the search box. Ideally I would like to be able to enter multiple search terms seperated by a comma or even just a space which returns all cases that contain these terms. The search function I have come up with based on information in these forums is:

SortByColumns(Search(Table1_1,TextSearchBox1.Text,"Abstract","Author","Supervisor(s)","Project_x0020_Title"),
"Year", If(SortDescending1, Descending, Ascending))

When I enter a term like "biofilm" in the box it searches the columns "Abstract","Author","Supervisor(s)" and "Project Title" and returns any case containing the word biofilm in these 4 columns.

This is great but ideally I would like to be able to enter multiple search terms in the text box, for example "biofilm", "Smith", "ecotoxicology" to return any cases which contain these three words. Is this possible to do in Powerapps? At the moment if I enter multiple terms and the words aren't consecutive then the search returns a blank. So for example if I enter "john" "smith", projects by john smith are returned; however if I enter "smith" "ecotoxicology" then there is no cases returned.

Thanks!

I got this working using collections (check this article and this post if you need more than 2000 rows in your collection) and @CalfordMath solution to filtering a gallery using search words in any order 🙂

I have 2 columns key words and questions. I am using the code:

If(IsBlank(TextInput2.Text), Questions, Search(Search(Questions,
First(TrimEnds(Split(TextInput2.Text, ","))).Result, "crff8_keywords", "crff8_question"),
Last(FirstN(TrimEnds(Split(TextInput2.Text, ",")), 2)).Result, "crff8_keywords", "crff8_question"))

However if i search by Agile, Sharepoint this is not working. It stops working after i put "," between the keywords.

Please suggest

@PK_Hongsolution does not work unless you are searching exact phrases.... Use @CalfordMath solution will work with the words searched in any order.... Also no need to separate your search terms with ","

Hi You can use the following Approach to meet your requirement with Split function in powerapps:

Filter(
AddColumns(
DataSource,
"found",
Sum(
ForAll(
Split(
TextInput24.Text,
" "
),
If(
IsBlank(
Find(
Lower(Result),
Lower(FieldName)
)
),
0,
CountRows(
Split(
TextInput24.Text,
" "
)
)-1
)
),
Value
)
),
found >= CountRows(
Split(
TextInput24.Text,
" "
)
)
)

This is brilliant, @CalfordMath -- just what I needed. Tweaked it a bit to work with a multi-select ComboBox and worked a treat... Thanks very much for sharing!

Hi @CalfordMath ,

can i check is there any way to filter multiple nonconsecutive keywords with the results highlighted? Thank you.

Not sure if you are still active @CalfordMath ...Your formula helps my use case and although your detailed explanation has been a learning experience, I have open questions on what "Results" means here. 

I am searching keywords, separated by commas, in two fields ("Name" and "Description"). I updated your code but still get an error. Do you see something obvious that you can call out? 

Filter(
    Columns,
    IsBlank(
        Find(
            "0",
            Concat(
                Filter(
                    Split(
                        SearchBar.Text,
                        "," //or any delimiter.
                    ),
                    !IsBlank(Result)
                ),
                If(
                    TrimEnds(Result) in Name || TrimEnds (Result) in Description, // etc.
                    "1",
                    "0"
                )
            )
        )
    )
)

@Sofiyan - believe they just recently updated all functions (including Split) that used to return Result and made them return Value, for uniformity across Power FX.

Try replacing Result with Value and see if that resolves the errors.
