How do you build a multi-criteria search engine in Excel?

You can build a multi-criteria search engine in Excel using FILTER to apply multiple logical conditions and CHOOSECOLS to control the output columns. This approach allows dynamic, real-time filtering without VBA, helper columns, or Power Query.

In this article, you will learn how to design a scalable, flexible, and fast search engine that allows users to search data using multiple criteria simultaneously—all with clean formulas and dynamic results. 🚀

📌 Why Build a Multi-Criteria Search Engine in Excel?

Traditional Excel tools like VLOOKUP, XLOOKUP, and INDEX-MATCH are excellent—but they fall short when:

• You need to search by multiple conditions
• Users want partial matches
• Results must auto-expand
• Columns need to be shown dynamically

That’s where FILTER + CHOOSECOLS shine.

Key Benefits 💡

• 🔄 Real-time results
• 🧠 Logic-driven filtering
• 📊 Auto-spilling tables
• ⚡ High performance on large datasets
• 🧩 No redundant helper columns

🧠 Core Concept: How This Search Engine Works

At a high level:

1. FILTER() applies multiple conditions to your dataset
2. CHOOSECOLS() controls which columns appear in the output
3. Boolean logic (*, +) combines criteria
4. Optional inputs allow flexible searching

📂 Sample Dataset Structure

Assume your raw data is in A1:H1000:

🧪 Step 1: Create User Input Cells 🧑‍💻

Place search inputs in clearly labeled cells:

These will drive the search logic.

🔧 Step 2: Basic FILTER Formula

Here’s a multi-criteria FILTER formula:

=FILTER(
  A2:H1000,
  (C2:C1000=K2)*
  (D2:D1000=K3)*
  (E2:E1000=K4)*
  (G2:G1000=K5)*
  (F2:F1000>=K6),
  "No matching records found"
)

📝 Explanation

• Each condition returns TRUE/FALSE
• * works as AND logic
• Only rows where all conditions are TRUE are returned

🔀 Step 3: Add Optional Criteria (Blank-Aware Search)

To allow blank inputs (very important!), modify the logic:

=FILTER(
  A2:H1000,
  ((K2="")+(C2:C1000=K2))*
  ((K3="")+(D2:D1000=K3))*
  ((K4="")+(E2:E1000=K4))*
  ((K5="")+(G2:G1000=K5))*
  ((K6="")+(F2:F1000>=K6))
)

Why This Works 🧠

• (K2="") returns TRUE when empty
• + acts as OR logic
• Blank inputs are ignored automatically

🎯 Step 4: Control Output Columns Using CHOOSECOLS

Let’s say you only want to display:

👉 Name

👉 Department

👉 Role

👉 Salary

Wrap the FILTER formula:

=CHOOSECOLS(
  FILTER(
    A2:H1000,
    ((K2="")+(C2:C1000=K2))*
    ((K3="")+(D2:D1000=K3))*
    ((K4="")+(E2:E1000=K4))*
    ((K5="")+(G2:G1000=K5))*
    ((K6="")+(F2:F1000>=K6))
  ),
  2,3,5,6
)

🚀 Result

• Clean, user-friendly output
• No duplicate or unnecessary columns
• Easy to rearrange columns later

🔍 Step 5: Add Partial Match Search (Advanced)

To enable contains-type searching, use SEARCH():

=FILTER(
  A2:H1000,
  ((K4="")+ISNUMBER(SEARCH(K4,E2:E1000)))
)

This allows users to type:

• “Man” → matches “Manager”
• “Dev” → matches “Developer”

Perfect for real-world search engines. 🔥

⚡ Performance Tips for Large Datasets

✔ Use Excel Tables (Ctrl + T)

✔ Avoid volatile functions

✔ Use CHOOSECOLS outside FILTER

✔ Keep ranges tight

✔ Prefer numeric comparisons where possible
