1.0.1

August 19, 2023

Added test containers for MySQL. Revised some tests for clock drift. Improved overall testing for clause string conversion.

1.0.0

July 13, 2023

Significant work on testing Searchlight:

  • Added integration tests for Postgres, MongoDB, and SQL Server.
  • Added SonarCloud for analyzing potential vulnerabilities.
  • Report an error when a compound clause contains both AND and OR statements. This prevents unclear order-of-operations risks when someone specifies (A and B or C).
  • Fixed issues with negated queries. If a user specifies "not eq"
  • Addressed test issues with dates and time zones and evaluation of nullability of generic collections vs databases
  • Addressed issues with escaping of string values; fixes issue where an end user searches for a string containing percentage signs

0.9.22

November 10, 2022

Updated some exceptions to include more readable error message values.

0.9.21

March 29, 2022

  • Implementation of Searchlight for MongoDB
  • All test cases run against MongoDB in the same form that they run against in-memory collections
  • Works using the official C# MongoDB driver
  • Refactored the test suite to make comparisons across different databases/executors easier

Future improvements planned for MongoDB:

  • Case insensitive string comparison
  • Searchlight collections support

0.9.20

March 15, 2022

  • Performance testing shows that a batch of six Parse calls takes about 24 microseconds
  • Based on performance testing, there's no reason to build libraries for any version other than NetStandard20
  • Added aliases for gte and lte criteria
  • Added icon thanks to https://icons8.com/icons/set/searchlight# 0.9.19

0.9.19

March 7, 2022

Added support for NetCoreApp 3.1 and NetStandard 2.0 frameworks. Removed dependency on System.Dynamic.Linq.Core.

0.9.18

March 1, 2022

Add support for the 'NOT IN' filter in SQL queries.

0.9.17

January 18, 2022

Small fix to allow page size of one.

0.9.16

December 14, 2021

Changes to engine-level configuration values.

  • Maximum parameter count and maximum page size values can be configured at the engine level.
  • Added support for SQL Server performance tuning features: NOCOUNT, READ UNCOMMITTED, and WITH NOLOCK.
  • NOCOUNT and READ UNCOMMITTED are enabled by default. Since Searchlight queries do not rely on "records affected", and since searchlight is a nondestructive query system, these options will reduce contention and enable higher performance queries. If you require precision in your query results, you can disable READ UNCOMMITTED at the engine level.
  • Added support for NOW date constant
  • Updated to support DotNet 6.0
  • Began work on Searchlight for MongoDB. Expect more soon!

0.9.15

0.9.14

October 11, 2021

  • Added friendly error message text for each Searchlight exception
  • Fixed bug where default sort could not contain direction
  • Refactoring work for the tokenizer and cleanup

0.9.13

September 29, 2021

  • The LINQ Executor now returns FetchResult<T> with pagination information.
  • Searchlight can now enforce a MaximumPageSize across all queries on the SearchlightEngine. The goal is for implementors to decide how much data is too much and be able to exercise control over API calls.
  • DefaultSort is required for a searchlight model. Omitting this value will throw an exception during construction of the SearchlightEngine. This is necessary to ensure consistency of pagination. Records not sorted will not paginate correctly.
  • All Searchlight errors now include XMLDOCs explaining the problem. A future improvement would be for errors to have a human-friendly string as well.

0.9.12

September 28, 2021

  • Fixed LINQ executor bug with handling of null pageNumber values in pagination
  • LINQ executor now works correctly with pagination and returns a FetchResult object with pagination information including total count

0.9.11

September 24, 2021

  • Added support for pagination for LINQ Executor

0.9.10

September 23, 2021

  • Fixed bug with foreign table SQL requesting data for multiple tables
  • Added tests to verify that multiple searchlight flags work as expected
  • Fixed issue where a searchlight flag without aliases caused a crash

0.9.8

September 23, 2021

Fixed compile issue where LINQ dynamic core was not referenced correctly

0.9.7

September 22, 2021

Searchlight queries now support date shorthand: TODAY, TOMORROW, YESTERDAY can be used as values for date criteria. This means you can now write queries such as date between yesterday and tomorrow. We may add more support for date constants in the future.

  • LINQ executor sorts results according to the same logic as the SQL executor
  • LINQ executor works correctly if you send in a null or filter statement
  • Recognizes "ascending" and "descending" in addition to "asc" and "desc" for sort orders
  • Removed references to Dapper, which is no longer required to compile

0.9.6

September 19, 2021

  • LINQ executor now uses case insensitive string comparison correctly

0.9.5

September 19, 2021

  • Added support for SearchlightFlags, a system you can use to detect options selected via the "$include" parameter
  • Added tests for flags and refactored the CommandCollection system for faster processing

0.9.4

August 16, 2021

  • Fix issue where FieldName in () could result in a null pointer exception

0.9.3

July 20, 2021

  • LINQ executor can now handle comparatives for strings such as >, >=, GTE, and so on

0.9.2

June 23, 2021

  • LINQ executor can handle in cluases for intrinsic data types with boxing
  • Added tests for decimals and integer in clause queries
  • Modified string operations to be case insensitive

  • Added support for In and NotEqual to LINQ executor

  • Update the method signature for LINQ querying to be similar to SQL.
  • Add foreign key functionality via SearchlightEngine
