## Introduction {#intro}

Go's emphasis on backwards compatibility is one of its key strengths.
There are, however, times when we cannot maintain complete compatibility.

    @Execute
    public JsonResponse<ApiResult> docs(final SearchBody body) {
        validateApi(body, messages -> {});

        if (StringUtil.isBlank(body.q)) {
            // query matches on all documents.
            body.q = Constants.MATCHES_ALL_QUERY;
        }

        final SearchRenderData renderData = new SearchRenderData();
        body.initialize();
        try {

Fess comprend également un Crawler, capable d'explorer les documents sur un [serveur web](https://fess.codelibs.org/14.17/admin/webconfig-guide.html), un [système de fichiers](https://fess.codelibs.org/14.17/admin/fileconfig-guide.html), ou un [Data Store](https://fess.codelibs.org/14.17/admin/dataconfig-guide.html)...

        }
        try {
            if (fessConfig.isThumbnailCrawlerEnabled()) {
                final ThumbnailManager thumbnailManager = ComponentUtil.getThumbnailManager();

MINIO_ETCD_CLIENT_CERT_KEY  (path)      client cert key for mTLS authentication
MINIO_ETCD_COMMENT          (sentence)  optionally add a comment to this setting
```

This behavior is consistent across all keys; each key self-documents itself with valid examples.
