# FindClaimsSearchCriteria

Request payload passed to `WorkerDataApiClient.FindClaims`, describing the fields a caller can populate to search for claims by worker identity, address, policy/account, and claim/check numbers.

## Purpose
- Carries the full set of optional search fields (worker name/DOB/tax ID, address, policy/account numbers, claim/check numbers, RTW user id) accepted by the Guidewire ClaimCenter `claim/search` endpoint.
- Controls result shaping via `ContainsOnly`, `MaxLimit`, and `FieldFilter`.

## Context
- Namespace: `SAIF.Data.Guidewire.Contracts`
- Assembly/package: `SAIF.Data.Guidewire` (packaged in `SAIF.SAIFCode.Core`)

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| ContainsOnly | `public bool ContainsOnly { get; set; }` | Requests contains-style (substring) matching rather than exact matching for the supplied search fields* |
| MaxLimit | `public int MaxLimit { get; set; }` | Caps the number of claim results returned by the search |
| FieldFilter | `public string FieldFilter { get; set; }` | Restricts which fields are returned on each matched claim summary* |
| AddressLine | `public string AddressLine { get; set; }` | Address line to match against; omitted from the serialized request body entirely when null (`[JsonIgnore(Condition = JsonIgnoreCondition.WhenWritingNull)]`) |
| CheckNumber | `public string CheckNumber { get; set; }` | Check number to match against |
| ClaimNumber | `public string ClaimNumber { get; set; }` | Claim number to match against |
| ParentAccount | `public string ParentAccount { get; set; }` | Parent account identifier to match against |
| PolicyNumber | `public string PolicyNumber { get; set; }` | Policy number to match against |
| RateAccount | `public string RateAccount { get; set; }` | Rate account identifier to match against |
| RtwUserId | `public string RtwUserId { get; set; }` | Return-to-work user id to match against |
| WorkerDateofBirth | `public string WorkerDateofBirth { get; set; }` | Worker date of birth to match against |
| WorkerFirstName | `public string WorkerFirstName { get; set; }` | Worker first name to match against |
| WorkerLastName | `public string WorkerLastName { get; set; }` | Worker last name to match against |
| WorkerMiddleName | `public string WorkerMiddleName { get; set; }` | Worker middle name to match against |
| WorkerTaxID | `public string WorkerTaxID { get; set; }` | Worker tax ID to match against |

## Behavioral notes
- This class has no behavior of its own; it is a plain data-transfer object serialized to JSON by `WorkerDataApiClient.FindClaims` before being POSTed to `claim/search`.
- Only `AddressLine` carries a `[JsonIgnore(Condition = JsonIgnoreCondition.WhenWritingNull)]` attribute (using `System.Text.Json`); the other string properties have no such attribute, so a null value in those fields is serialized as JSON `null` rather than omitted, unlike `AddressLine`.
- `WorkerDateofBirth` is typed as `string`, not `DateTime`, so callers are responsible for supplying it in whatever date format the Guidewire search endpoint expects*.

## Constraints and usage notes
- All properties are optional/mutable and default to their CLR defaults (`false`, `0`, or `null`) when not explicitly set.
- Note the `[JsonIgnore]` attribute here uses `System.Text.Json.Serialization`, whereas most serialization elsewhere in this library's clients uses `Newtonsoft.Json`; `WorkerDataApiClient.FindClaims` serializes this type with `Newtonsoft.Json.JsonConvert.SerializeObject`, which does not honor `System.Text.Json`'s `[JsonIgnore]` attribute, so `AddressLine` is serialized as `null` (not omitted) in practice**.
