Analyzer components (tokenizer, filters) in Elasticsearch - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a standard tokenizer in an Elasticsearch analyzer.

Elasticsearch

"analyzer": { "my_analyzer": { "type": "custom", "tokenizer": "[1]" } }

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'keyword' tokenizer which does not split text.

Using 'whitespace' tokenizer which only splits on spaces.

The standard tokenizer splits text into terms on word boundaries, which is the default and most common tokenizer.

2fill in blank

medium

Complete the code to add a lowercase filter to the analyzer filters list.

Elasticsearch

"analyzer": { "my_analyzer": { "type": "custom", "tokenizer": "standard", "filter": ["[1]"] } }

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'stop' filter which removes common words.

Using 'uppercase' filter which converts tokens to uppercase.

The lowercase filter converts all tokens to lowercase, helping with case-insensitive search.

3fill in blank

hard

Fix the error in the filter list by choosing the correct filter name to remove stop words.

Elasticsearch

"analyzer": { "my_analyzer": { "type": "custom", "tokenizer": "standard", "filter": ["[1]"] } }

Drag options to blanks, or click blank then click option'

Dstop

💡 Hint

Common Mistakes

Using 'lowercase' filter which only changes case.

Using 'porter_stem' which reduces words to their root form.

The stop filter removes common stop words like 'the', 'and', 'is' from the tokens.

4fill in blank

hard

Fill the three blanks to create an analyzer that uses the whitespace tokenizer and applies lowercase and asciifolding filters.

Elasticsearch

"analyzer": { "my_analyzer": { "type": "custom", "tokenizer": "[1]", "filter": ["[2]", "[3]"] } }

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'standard' tokenizer instead of 'whitespace'.

Mixing up filter order or names.

The whitespace tokenizer splits text on spaces. The lowercase filter converts tokens to lowercase, and asciifolding removes accents from characters.

5fill in blank

hard

Fill all four blanks to define an analyzer with the standard tokenizer and filters: lowercase, stop, and porter_stem.

Elasticsearch

"analyzer": { "my_analyzer": { "type": "custom", "tokenizer": "[1]", "filter": ["[2]", "[3]", "[4]"] } }

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Wrong tokenizer name.

Incorrect filter order or missing filters.

This analyzer uses the standard tokenizer, then applies lowercase to normalize case, stop to remove common words, and porter_stem to reduce words to their root form.
