## Filter or Extract with a Partial Match

Assume you have a table consisting of a few cells having few values, and you want to filter out the set of records with the partial match. You might take it easy and would prefer to manually filter out the desired partial matching values into another table without any need for the formula; then congratulations because you are thinking right.

But let me add that it would be a big deal while dealing with a bulk of data in the table, and then doing this bulky task manually would be a foolish decision.

But there isn’t any need to worry about it because after carefully reading this article filtering out the set of records with the aid of partial matches will be a piece of cake for you.

So let’s get straight into it!

## General Formula:

You can use the FILTER function in combination with the SEARCH function to choose data records based on a partial match. The formula in E4 is written as follows:

`=FILTER(Data_range,ISNUMBER(SEARCH(B2,Filter_range))*(B2<>""),"Not Found")`

Note: Data_range is name range for A2:C9, and Filter_range is antoehr name range for B2:B9.

## Let’s See How This Formula Works

The motive is to extract a collection of records that match a partial text string in this example. We match one column in the data range A2:C9 or the “Region” column. The FILTER function (new in Excel 365) retrieves matched data from a range based on a logical filter, which is at the heart of this formula:

`=FILTER(filter_data,filter_logic)`

The task in this example is to build the logic required to match records based on a partial match. Because the FILTER function does not handle wildcards, we must use an alternative technique. In this situation, we use the SEARCH function in conjunction with the ISNUMBER function as follows:

`=ISNUMBER(SEARCH(B2,Filter_range))`

The SEARCH function seeks text input in cell E2 within the Filter_range name range. SEARCH returns the position of a result in the text if it finds one.

If SEARCH formula does not yield any results, it returns the `#VALUE!` error:

We have a match if SEARCH returns a number. Otherwise, we don’t have a match. We wrap the SEARCH function within the ISNUMBER function to transform this result into a simple TRUE/FALSE value. Only when SEARCH returns a number will ISNUMBER return TRUE.

We aren’t utilizing a wildcard like (“*”) to achieve a partial match, but the SEARCH + ISNUMBER combination acts similarly. SEARCH function will return a number if the search string is found anywhere in the text, and ISNUMBER will return TRUE if the search string is found anywhere in the text.

`=FILTER(Data_range,ISNUMBER(SEARCH(B2,Filter_range)))`

We now have a workable formula, but we still need to clean up a few things. First, if the FILTER function returns no results, it will produce a `#CALC!` error. We would add a text message for the “if_empty” argument to deliver a friendlier message:

`=FILTER(Data_range,ISNUMBER(SEARCH(B2,Filter_range))*(B2<>""),"Not Found")`

Finally, we must deal with the circumstance where the search string in E2 is blank. Surprisingly, if the search text is an empty string, the SEARCH function will return the value 1.

If field B2 is empty, FILTER will return all results since ISNUMBER will joyfully return TRUE for number 1. To avoid this behavior, we add the following logic to the original logical expression:

`=ISNUMBER(SEARCH(B2,Filter_range))*(B2<>"")`

When B2 is not empty, the expression B2<>”” yields TRUE; otherwise, it returns FALSE. By the original SEARCH + ISNUMBER expression, when we would multiply the results of this expression, all TRUE results are “canceled out” when B2 is empty. This is a variation on Boolean logic.

## Extract All Partial Match Using Index and Match function

Only Excel 365 supports the FILTER feature. It is feasible to put up a partial match formula in previous versions of Excel to produce more than one match, but it is more complicated. This following formula demonstrates one method based on INDEX and MATCH.

`=INDEX(\$B\$1:\$B\$5,AGGREGATE(15,6,(ROW(\$B\$1:\$B\$5)-ROW(\$B\$1)+1)/ISNUMBER(SEARCH(\$D\$1,\$B\$1:\$B\$5)),E2))`

## Extract all Partial Matches

Just assume that you have a range of data that contains a text string and you want to extract the few partial matches into another separate range of cells; then you might think that it’s not a big deal; because you would prefer to manually extract the few partial matches into another separate range of cells without any need of the formula;

Then congratulations because you are thinking right, but let me add up that it would be a big deal to extract the multiple partial matches into another separate range of cells and doing it manually would be a foolish attempt because you would get tired of it and would never complete your work on time.

But don’t be worry about it because after carefully reading this article, extracting multiple partial matches into another range of cells would become a piece of cake for you.

So let’s dive into the article to take you out of this fix.

## General formula

The Following formula would help you out for extracting multiple partial matches into another separate range of cells:

`=INDEX(\$B\$1:\$B\$5,AGGREGATE(15,6,(ROW(\$B\$1:\$B\$5)-ROW(\$B\$1)+1)/ISNUMBER(SEARCH(\$D\$1,\$B\$1:\$B\$5)),E2))`

## Syntax Explanations

Before going into the explanation of the formula for getting the work done efficiently, we must understand each syntax which would make it easy for you that how each syntax contributes to extracting multiple partial matches into a separate range or list of cells:

• `INDEX`: In a range or array, this index function contributes to returning the value at a given position.
• `AGGREGATE`: This function contributes to returning the aggregate result in a database or list of values in the excel sheet.
• `ROW`: In Excel, this Row function contributes toreturning the row number as a reference.
• `Absolute Reference`: The Absolute referenceis nothing but an actual fixed location in a worksheet.
• `ISNUMBER`: This function contributes to returns TRUE when a cell contains a number and FALSE if there is no number.
• `SEARCH`: This function contributes to locating the character between two text strings and returns to the number of the starting position of the first text string from the first character of the second text string.
• `Comma symbol` (,): In Excel, this comma symbol acts as a separator that helps to separate a list of values.
• `Minus Operator` (-): This minus symbol contributes to subtracting any two values.
• `Parenthesis` (): The core purpose of this Parenthesis symbol is to group the elements and to separate them from the rest of the elements.
• `Plus operator` (+): This plus operator adds the values.
• `Division` (/): This division symbol is used for dividing values or numbers.

## Let’s See How This Formula Works:

The INDEX function is the primary function having AGGREGATE, which is highly useful to figure out the matches for each row in the extracted area:

`=INDEX(\$B\$1:\$B\$5,matched_values)`

Almost all of the work is to determine and report which rows in “`\$B\$1:\$B\$5`” match the search string and report the position of each matching value to INDEX. This is accomplished by configuring the AGGREGATE function as follows:

`=AGGREGATE(15,6,(ROW(\$B\$1:\$B\$5)-ROW(\$B\$1)+1)/ISNUMBER(SEARCH(\$D\$1,\$B\$1:\$B\$5)),E2)`

The very first input or argument, which is `15`, instructs AGGREGATE to return the nth smallest values.

The second argument, `6`, specifies whether or not to ignore mistakes.

The third argument is an expression that returns an array of results that match.

The fourth input, `E2`, it specifies the “nth” value.

AGGREGATE works on arrays, and for the third argument inside AGGREGATE, the expression below builds an array :

`={(ROW(\$B\$1:\$B\$5)-ROW(\$B\$1)+1)/ISNUMBER(SEARCH(\$D\$1,\$B\$1:\$B\$5))}}`

In this case, the ROW function is used to build an array of relative row numbers, as that’s why SEARCH and ISNUMBER are combined to match the search string against values in the data, resulting in an array of TRUE and FALSE values.

TRUE behaves as 1 in this math operation, while FALSE behaves as 0. As a result, row numbers with a positive match are divided by 1 and survive the operation, whereas row numbers with non-matching values are destroyed and become `#DIV/0 `errors. AGGREGATE is configured to ignore errors; it ignores #DIV/0 errors and returns the “nth” smallest number from the remaining values.

## Alternative Formula with SMALL Function

You can also use an alternative formula which is based on SMALL function and IF Function to achieve the same result:

`=INDEX(\$B\$1:\$B\$5,SMALL(IF(ISNUMBER(SEARCH(\$D\$1, \$B\$1:\$B\$5)),ROW(\$B\$1:\$B\$5)-ROW(\$B\$1)+1),E2))`

Note: this is an array formula, and to get the work done, please enter it with `Control` `+` `Shift` `+` `Enter`.
