Definition: The fixed part of a query that remains constant, regardless of specific data or user input.

⚖️ Contrast

• ✅ Non-Variable Portion: Stays the same in specific types of queries.
• 🔀 Variable Portion: Changes based on user input or specific conditions.

📝 Example: Search Query Template

• 📌 Template: "Causes of $X"
• 🟢 Non-variable portion: "Causes "
• 🔵 Variable portion: "$X"

🔧 Use in Information Retrieval

In this template, the non-variable portion "Causes" remains unchanged, while the variable portion "$X" can be substituted with different terms to form specific queries, such as:

• 😴 "Causes of sleepiness"
• 🐢 "Causes of sluggishness"
• 💪 "Causes of weakness"

By utilizing such templates, search systems can better understand and anticipate user intent, allowing them to provide more accurate and relevant results. For instance, recognizing that queries like "Causes of sleepiness" and "Causes of weakness" follow the "Causes of $X" template enables the system to identify the user's intent to learn about the causes of specific conditions.

🎯 Benefits

• 🔎 Identifying user intent: Helps refine search queries for better accuracy.
• 📊 Extracting relevant information: Enhances search engine efficiency.
• 🔄 Creating multiple queries: Allows generating diverse searches by changing the variable portion while keeping the core query structure unchanged.
