Fail to Compile Main Branch

[zengyr49]

on "main" branch

sentences like:
ai/spring/demo/ai/playground/Application.java:46
vectorStore.similaritySearch("Cancelling Bookings").forEach(doc -> { logger.info("Similar Document: {}", doc.getContents()); });
and
ai/spring/demo/ai/playground/services/CustomerSupportAssistant.java:63
new QuestionAnswerAdvisor(vectorStore, SearchRequest.defaults()), // RAG

will be marked by IDEA as no such method

I think these usages should be modified in this project.

doc.getContents() should be doc.getText()
SearchRequest.defaults() should be SearchRequest.builder().build()

if these modifications are wrong, please type your correction below.
