💡 Hint

Common Mistakes

Using a different phrase than 'search text' in the match query.

Putting the phrase outside the quotes.

The dis_max query combines multiple queries and uses the highest score. Here, the first match query should search for "search text" in the title field.

      "queries": [
        { "match": { "title": "search text" } },

💡 Hint

Common Mistakes

Using an integer instead of a decimal.

Setting tie_breaker to 0 or 1 which changes behavior drastically.

The tie_breaker parameter controls how much the scores of non-best matching queries contribute. Setting it to 0.7 means 70% of the other scores add to the max score.

Fix the error in the dis_max query by completing the missing field name.

Elasticsearch

{
  "query": {
    "dis_max": {
      "queries": [
        { "match": { "[1]": "search text" } },
        { "match": { "description": "search text" } }
      ]
    }
  }

💡 Hint

Common Mistakes

Using a field name that does not exist in the index.

Leaving the field name blank or misspelled.

The first match query must specify the field name to search. "title" is the correct field name here.

4fill in blank

hard

Fill both blanks to create a dis_max query with a tie_breaker and two match queries on 'title' and 'content'.

Elasticsearch

{
  "query": {
    "dis_max": {
      "tie_breaker": [1],
      "queries": [
        { "match": { "title": "search text" } },
        { "match": { "[2]": "search text" } }
      ]
    }

💡 Hint

Common Mistakes

Using an invalid tie_breaker value.

Using the wrong field name for the second match query.

The tie_breaker is set to 0.5 to balance scores. The second match query searches the 'content' field.

5fill in blank

hard

Fill all three blanks to build a dis_max query with tie_breaker, boost, and two match queries on 'title' and 'summary'.

Elasticsearch

{
  "query": {
    "dis_max": {
      "tie_breaker": [1],
      "boost": [2],
      "queries": [
        { "match": { "title": "search text" } },
        { "match": { "[3]": "search text" } }
      ]
    }
  }
}

💡 Hint

Common Mistakes

Mixing up boost and tie_breaker values.

Using incorrect field names in match queries.

The tie_breaker is 0.3 to allow some contribution from other queries. The boost is 1.5 to increase overall score weight. The second match query searches the 'summary' field.
