Search Query Examples and Results

📘

Tetra Data Platform (TDP) Versions

• For TDP versions >= 3.2, please continue with this page.
• For TDP versions < 3.2, please review this page.

This page describes Search query examples (and their results) that you can create using the Tetra Data Platform (TDP). For information about using the TetraScience API to run searches, see the TetraScience API Documentation.

You can enter text directly in the Search bar to search. Results that include Intermediate Data Schema (IDS) output files also return the associated RAW input files.

When running searches, keep in mind the following:

• If you search without specifying a field, then the value is case-insensitive.
• If you search for a specific field, then the value you enter must be the exact value.

Reserved Characters

The Search feature in the Tetra Data Platform recognizes these reserved characters:

📘

Reserved Characters

Reserved characters are: + - = && || > < ! ( ) { } [ ] ^ " ~ * ? : \ /

To use any character which functions as an operator in the query itself, use a leading backslash to escape them.

For example, to search for (1+1)=2, you must enter the query as:
\(1\+1\)\=2

The escape characters are dropped when viewed on the web, and should also be escaped.

Search Text Examples and Explanation

This table provides Search text examples and explains what the search process is when searching through the files.

Plain Text Processing Examples

Plain text entered in the Search bar is analyzed using Elasticsearch's Standard Tokenizer. Word boundaries are determined based on the
Unicode Text Segmentation algorithm, as specified in Unicode Standard Annex #29.

This means that any searches that contain spaces, hyphens, '+', and some other common symbols, are broken down into terms; however, underscores are not. For this sentence example:

The 2 QUICK Brown-Foxes jumped_over the lazy dog's bone.

The sentence is broken down into these terms:

[ The, 2, QUICK, Brown, Foxes, jumped_over, the, lazy, dog's, bone ]

This may make exact-match searches unpredictable.
In this UUID example, you are trying to match an exact ID that includes hyphens:

576fd742-c1a6-4fb4-9ecb-398d53e4addb

This will match any data including:

"576fd742", "c1a6", "4fb4", "9ecb", "398d53e4addb"

We recommend that when you want to query for an exact match for such a value, you should add quotes around the search string:

"576fd742-c1a6-4fb4-9ecb-398d53e4addb"

This causes Elasticsearch to ignore any word boundaries and generate a more appropriate search result. However, this behavior exists for "free-text" searches only. Searches on exact fields are analyzed based on that particular field's type. For example, this query will use the Keyword tokenizer because this field is a keyword type:

source.type.executionId: 576fd742-c1a6-4fb4-9ecb-398d53e4addb

By default, the "Keyword" tokenizer does not adhere to the same word boundaries rules as the "Standard" tokenizer. An exact-match query without quotations works as expected.

Nested Types

Elasticsearch nested field types allow arrays of objects to be indexed in a way that they can be queried independently of each other. You can search for Elasticsearch nested field types either in the Search bar or Query DSL queries.

For more information about searching for nested field types in the TDP, see How to Apply Filters to Search by Schema Data and Search by Using Elasticsearch Query DSL. For more information about nested field types, see Nested field types in the Elasticsearch documentation.

Wildcard Searches

Don’t use a wildcard prefix (*) in searches. Instead, do either of the following:

• In the Search bar, enter either parts of a file path (separated by spaces), or a complete file path.
• Run a Query DSL query by using the Label & Advanced Filters menu

🚧

IMPORTANT

Queries that include wildcards aren’t as effective, take longer to run, and require more computing resources.

Group Search Terms Examples

You use () parentheses to group words or operations.

Specify a Range Examples

You can specify ranges for: date, numeric, or string fields. You specify inclusive ranges with square brackets [min TO max], and exclusive ranges with curly brackets {min TO max}.
